The Vinohrady Variation

I am not sure if Lubomir Kavalek's name for 1.e4 c5 2.Nc3 Nc6 3.g4!? (which he analyzes in his Washington Post chess column today) will be adopted in Jeroen Boesch's Secrets of Opening Surprises volume 5 (where, Kavalek says, the line will likely be discussed). I rather prefer Andrew Martin's "My Hand Slipped!" as a description of that impudent advance. In any event, neither Martin nor Kavalek discuss the most challenging response, which must be 3...e6! (as mentioned in the ChessPublishing Forum), with the idea of 4.Bg2 (4.d3 d5 =) 4...h5! 5.gxh5 Nf6 etc. What do you suppose Boesch will recommend here?
