Hmm. Thanks for the pointer. Second time tonight I've discovered that I'm being redundant
It looks like that VNC server requires the Hijack kernel, which, as far as I can tell from searching around here, hasn't been ported yet. Since mine doesn't (currently) handle input, it doesn't need the Hijack kernel's button injector mechanisms.
I might wade into hacking up empegVNC to decouple its input handling, though. That way, it would be of use to people with and without the Hijack kernel, and also of use to hackers building "from scratch" (ie: discarding the monolithic player app).
Then again, I -could- just get back to my real work
