Black's problem piece in the Exchange Variation of the Queen's Gambit is the bishop on c8. The point of 6.Qc2 is to embarrass the bishop by taking away its best square: Eric's 6...g6 is a radical attempt to solve the problem. (I've tried it more than once myself: NM Steve Tennant swept me off the board at a Western Open some years ago from the position after 8.Qb3, which forces Black to weaken the queenside pawns slightly.)
FM Jorge Peleaz really played a model game with the White pieces. Once the hanging pawns are forced into the unfavorable c4-d5 formation, the bishop on e6 is much less powerful than the dancing knight. 46.f5! is real purty.
If Black can find a way to get away with this line, the 6...g6 idea is golden. Until then, there's always 6...Be7.

Isn't 6... g6 actually a serious blunder. I think that 7. Nxd5! wins for white. I was suprised during the game to see both players miss this tactic.
Hmm. Can Black get comp with ...Bf5? E.g., 7.Nxd5 cxd5 8.Bxf6 Bf5 9.Qa4+ Bd7 and maybe Black has some comp?
Nazar Firman (who was in Chicago for awhile some years ago) has experimented with 6...h6 (idea 7.Bh4 g6).
Hmm. 7.Nxd5 cxd5 8.Bxf6 Bf5 9.Bxd8 chomp. What a fish I am.
Yeah. I think g6 in the game position is just an opening trap. If black wants a chance to equalize with g6 then he has to try a different move order so that Be7 and Nf3 are inserted. In the game continuation I think that black has to accept the bad light squared bishop.

Hmm again: 6...g6 7.Nxd5 Qxd5! 8.Bxf6 Bb4+ 9.Kd1 O-O! and Black has comp: Houdini.
10.e4 Re8!, or so the laptop tells me.
I still like white after meeting Re8 with Bd3, but I admit that the position is complicated. I grew up with the king's gambit so having central control and an extra pawn sounds well worth the king in the center. Usually there you are down the pawn with a position like this. I can see why, though, someone might prefer e3 to avoid the mess.
7.e3 is usually played, including by GMs like Hort. I could only find two games online with 7.Nxd5!?, which are at http://www.chessgames.com/perl/chessgame?gid=1348377 and http://www.365chess.com/view_game.php?g=2919731.
Evgeny Vladimirov, a strong Russian GM, won quickly with the move: 7...Qxd5 8.Bxf6 Bb4+ 9.Kd1 O-O 10.e4 Re8 11.Bd3 Bf5 12.f3 Nd7 13.Ne2 Nxf6 14.exd5 Nxd5 15.Qb1 c5 16.Bxf5 Ne3+ 17.Kc1 Nxf5 18.a3 Rxe2 19.axb4 c4 20.Rd1 Rc8 21.Ra3 Rd8 22.d5 Nd6 23.Rc3 1-0 Vladimirov-Diaz, Capablanca Memorial 1986
White deviated and lost with 10.Qb3? Qxb3+! 11.axb3 Be6 12.Kc2 Nd7 13.Bg5 c5! 14.Nf3 Rfc8 15.d5 Bxd5 16.e3 f6 17.Bf4 Nb6 18.Rd1 Be6 19.e4 c4 20.Nd4 cxb3+ 21.Kb1 Bf7 22.Be2 g5 23.Nb5 Rc2 24.Bd3 Rac8 25.Rc1 Bc4 26.Rhd1 Bd2 27.Rxd2 Rxc1+ 28. Kxc1 Bxd3+ 29.Nc3 Bxe4 30.f3 Bc6 31.Rd6 Kf7 32.Bg3 Nc4 33.Rd4 Ne3 34.Bf2 Nxg2 35.f4 g4 0-1 in Sarkar (2375)-Annakov (2489), Foxwoods Open 2004.
Note that White also has another try, 7.Bxf6?! Qxf6 8.Nd5, but this only equalizes at best after 8...Qxd4! 9.Rd1 (9.Nc7+? Kd8! 10.Nxa8? Bb4+ 0-1; 9.Qe4+ Qxe4 10.Nf6+ is better for Black - bishop pair) Bb4+ 10.Nxb4 Qxb4+ 11.Qd2.
