These are all interesting playable options, decent stuff.

My most recent victory with this system (Some Black players will continue with an early d7-d5-d4)
The Labourdonnais French is playable, but these moves as a 'system' against the Caro-Kann, Scandinavian, and Sicilian just doesn't work.
1.e4 c5 2.f4 d5 3.e5? Nc6 4.Nf3 Bg4! will be played by anyone who understands the opening. There is a real danger that White will end up in a middlegame where his Kingside is totally blockaded on the light squares, but Black's Queenside is still mobile (regard the pawn duo c5-d5) and can support an advance.

10...Qb6 obvious improvement to preserve Black's flexibility.
Even after 10...Nf5 11.Bxc6+ bxc6 12.Na3 Qb6, though, Black is just strategically better. White has no way to break the Kingside blockade. Maybe even the immediate 12...c4 is possible as a positional pawn sac (Black intends to take on a3 if allowed, since his N will be much stronger than White's bishop in the endgame) White would really like an exchange of Knights, but Black can either avoid it, or reinforce the N with ..g6.

GreenCastleBlock,
I gave 10...Nf5, because it was played in the only game I could find. After 11.Lxc6+ bxc6 12.Na3, which was not played in that game, the move with the Queen 12...Qb6 is one of the good possibilities for Black. After 12...c4 in attempt to take White's Knight on a3 White can go on with the tactic 13.Nxc4! dxc4 14.Qxc6+ Ke7 15.Qb7+ Kd8 with a perpetual check. After 13.c4 Rb8 14.Nc2 the game should be level.
After 10...Qb6 White can continue with 11.Na3, for example: 11...Nf5 12.Be3 and the game is still equal.
Of course thanks to the Black pawn on h4 the Kingside is blockaded, so White should have to look elsewhere to make any progress.
pfren,
5...h5 is just one of the possible continuation and at the moment analyses of other possibilities like 5...e6, 5...Nh6, ... are still in progress. 
Anyway, both thanks for the contributions sofar.
First of all, sorry for 12...c4, that move is a blunder (although a well-motivated one; I wanted to stop 13.c4) After 12..Qb6 13.c4 Black should develop with Be7, it is probable that a R belongs on b8 but no reason to put it there yet.
Secondly, you keep saying 'the position is equal' without giving any reasoning. I disagree; for the reasons that I gave in my last posts, both after 10...Qb6 11.Na3 and after the game continuation after 12...Qb6. As you admitted, White is not doing anything on the Kingside. The center is closed, so that leaves the Queenside where Black has more space. Hence, Black has the advantage.
Basically after 4...Bg4 Black's problems are more or less solved, which is why you're having trouble finding games between high level players - they won't touch this with White.

The reasons why I preffered 13...Rb8 are: first Bf8-e7 still can be played, second after 13...d4 (or somewhere later in the game) 14.Pc2 a5 15.Ld2 Qxb2?? White has 16.Qxc6+ plus Dc6xa8+ and third White still has a Qf3-g4 at his disposal, so Black don't have to commit hemself to play Bf8-e7-f8 or the little weakening g7-g6. Of course d5-d4 isn't a good idea because it allows White to put the Queen or the Knight on e4.
On the other hand, Black's mobility on the Queenside is limited because White can block Black's a-pawn with a simple a2-a3. Maybe the position is dead draw after 12...Qb6. Like I stated before: "As it were he (White) digs himself in as a mole and wait for a opportunity to come on the surface." And probably there's no real opportinity for White after 4...Lg4 plus 5...h5!.
And yes, you are right: because of 4...Lg4, 5...h5! plus h5-h4 the main goal, an attack on the Kingside, is vaporised and I am already thinking to throw away the whole idea with 4.Nf3 (not the system yet ) and replace with something else.

pfren,
After 5...e6 or 5...Nh6 my software sooner or later recommend the Kingsside blocking h7-h5, after which we will reach the same or simular postions as after 5...h5.
On the other hand, most of the opponents of my modest level rarely play 4...Bg4 in combination with h7-h5 and continue with 4...e6 with a transposition to the French.
Not sure if Ronaldo
Not only against Sicilian, but the system is also usefull against any other Black defence except 1...e5, 1...f5 (Fred defence), maybe the ugly 1...f6 and 1...Nf6 (Alekhine defence). It avoids studying shiploads of theorybooks.
