Ultra mobile should not be an issue but we haven't much data to offer here. In cases like this, we are always happy to offer a free test copy for you to play with--and with extra enthusiasm if promise you'll tell us what happens!

With respect to handhelds (treos, pocket pcs, iPhones and such), no not yet--although that is certainly a direction we are pursuing. Currently, whatever machine you use must have a fully functional version of Windows. It can't be crippled in some way. If you can load and run pretty much any other Windows application on it, then there is a very good chance the MediaLab will run just fine on it. Don't think here about Microsoft programs, think more in terms of programs like Photoshop, SPSS, SAS and that sort of thing.
