Speed should be the only issue. My understanding is that all of the dependencies are GPL, so you should be able to get the source code and I don\'t think it should be a problem to cross compile. (By not a problem, I mean it is technicaly possible, it\'s probably a huge pain in the ass, but you could do it)
Of course, I\'m sure there are pim programs with fewer dependencies, but I know evolution is nice. If you do get it all cross compiled with all the libs and other dependencies working, be darn sure you share, I\'m sure there\'s a lot ofother evo users that would thinkyou were a God.
