With the exception of "and mobile devices", it happens every day. For
most mobile devices, though, you're going to have to do this separately.
You can certainly use J2ME and MIDP to develop for a lot of mobile
devices at once; but that code will need to be somewhat different from
your code for desktop operating systems.

Installation will also be a trick for mobile devices. Generally, if the
device can run J2ME code, then there will be some way to get J2ME code
onto it... but it may involve jumping through hoops.
