The places you'll most often have trouble with embedded devices
is:

*) Trying to write cache or temp files too often, wearing out your
media.  If the device uses flash memory only, then you need to write
to RAM disk for your temp files instead.

*) Graphics operations.  A lot of the small devices run Maemo or
Qtopia.  You don't have X11 underneath, just Gtk on the one, or Qt
on the other.  Your apps need to be written to use the proper one.

Perl should work if you have the memory for it.  MySQL may work if
you're careful about where and how often it's writing files.  GD
probably depends on X11 being present?
