I do, but only in terms of BASIC. And HTML.
Things are rarely guaranteed to "Recompile", and if they did, they'd only work on similar operating systems.
For example, A VGA res MSN program (hypothetical) may very well recompile from your KDE desktop to your Zaurus, but it won't run without the required OS features. E.G. X desktop, QT. . You could have it on PDAXROM or OZ/GPE but not on a Qtopia based rom such as Sharp Default, Cacko, or OZ/OPIE. The X desktop is a completely different GUI system to Qtopia after all.
