OK, fiddled around a bit with the rim concept but code was getting a bit too complex (I am trying to KISS per the concept of an easy port to WP7) so I have put ot on hold until we see what is around the corner.
Thanks for the great feedback..
OK, Last time I am going to bump this topic (it just feels wrong for mew to do that all the time).
I have succesfully got the app working on the WP7 phone emulator (with a couple of issues)
Next step (after sorting those issues) is to investigate posting the app onto the marketplace (not sure what the pre-release story is for that just at the moment)
