Indeed, VRPC will always be an ARM emulator. But the point I'm getting at is that VA don't want to release a Linux version of VRPC because of the support headaches. So I was thinking of ways VRPC could run on Linux by putting in another layer between it and the host OS. This means either tricking VRPC into thinking it's running on Windows (the WINE route), or coming up with a Linux version of VRPC which runs on one fixed OS installation on one fixed hardware platform (that 'emulated' by the virtualiser). Any support headaches are therefore transferred to the virtualiser, which has a much larger user base. And if the virtualiser is multi-platform, it'll run on other OSs (eg Mac OS X/x86) so VA only need release one version of VRPC.
(I suspect the WINE route is probably much less work)
