Verification of computer programs ratings

There are continuing discussions if the today chess programs ratings (over 3000) are real or just a result of inflation, since the programs are playing only between themselves and not against human grandmasters.

This could be verified by matching a GM with a program having the same rating on the well-known computer-chess lists like SSDF or CCRL, i.e. lower than 3000. Then the result of their games will show if the chess-program rating is over-(or under-?) estimated.

Is there any GM willing to participate in such a match?
