Just to add to this, if it would be easy to implement,
would it be feesible to do a blanket launch for an entire
rom folder? Basically you would set a rom folder in XBMC,
and then specify the program used to launch any file from
that folder with (the relevent emulator). This would
allow for icon based selection (namely box art, or even
cart scans for that extra effect) for any rom that runs in
an Xport emulator. That covers a LOT of different
systems, and would really spice up the XBMC experience.

that is exactally what i was going to do, i also need the
same feature (i like to keep things very organized). ill
begin work today and keep you posted!
So barring any unforseen problems, looks like we'll have icon based rom selection from XBMC!!! Only downside is that the XBMC is on the freeze/bug bash for now, so I don't know how long until they're back to normal business.
