It would be great if one would:
- be able to play Playstation games upon inserting game disc (or loading it from database)
- simply connect Dual Shock 3 or Wiimote etc.
- be able to launch games from unified interface be it native Linux/Playstation or other games and play them through thin clients (unforeseen!)
There are mature emulators out there. Even Playstation 2 emulation is possible (less mature) on strong hardware. PCSX emulating Playstation 1 on the other hand should not even need original BIOS file.
