I have seen on one of the other e2 forums that someone has managed to get a SNES emulator working on his MIPS based STB. This is something that I think could be built upon and if there was ever support for console emulators added to the Vix build it would make it a complete entertainment centre. TV, XBMC and Emulators in one STB = perfection
A google search for 'Xcore Tomcat' brings up youtube videos of it in action. An init4 command is sent to kill enigma and then a command to launch the snes9x emulator and hey presto - the guy has mario kart up and running!
