until the at3+ format's reverse engineered/understood enough to decode it, i doubt it.
if the linux version could run dll files (which i'm guessing it can't), once the soundforge dll library's understood and implemented without the need for external exes maybe that'd work, but until then everything relies on stuff like sonicstage/soundforge and a bunch of closed source homebrew exes that use sony's libraries to decode the sounds after they're extracted on the fly.
i don't think sony ever released linux-compatible version of their programs.
