LSB 3, on the other hand, is going to add Gnome support, so they're at least thinking about the desktop now. (Your other objections - FreeType, fontconfig, libjpeg, OpenSSL, etc - could be packaged along with an LSB implementation of Wine, so they're not really an issue.)
Forgive the slight shift to off topic, but a while back, I asked the LSB if they'd consider adding Wine to the app-battery (standard tests required for LSB certification).
They were actually quite open to the notion; Alexandre was working with someone technical on the challenges involved.
Candidly, I dropped the ball (got too busy :-( ), but if someone else was willing to work that through, boy would that be nice.
Cheers,
Jer
