You could check out this thread:
http://forum.team-mediaportal.com/ph...1.html?t=14431 if you search on "touchscreen" it appears there are a few people working on a touchscreen skin. One even for their car computer. Ask around and see if maybe someone has completed such a skin but hasn't posted it back to the website. It would be nice if they have a skin completed to post it here.
