Yeah, In my view, the lack of out of the box support for a shared
enviroment is one of its downfalls. Not a big issue to compile the same
version for a desktop, as it doesnt take that long to compile, but still

I currently use MythWeb on an IPad to do most of my scheduling changes,
but I agree the simple setup of an extra frontend on Myth is definately
something that has been done right.

Would love to here how this goes. After 6 years running Myth for all
our TV usage (the entire lifetime of my children), its might be a trying
time switching to XBMC.
