Opie (see ) can run on top of familiar. Consider OpenZaurus 
or OpenEmbedded as an alternative solution to familiar, which
comes with Opie  as well and may run on the ipaq (unsure).
Unfortunately, i don't know familiar, so I cannot provide comparisons.

It depends. If you run X on your PDA (which is usually not the case),
many applications should work and are already ported. There's a
debian distribution (unofficial) for arm PDAs .
But native Linux applications to not fit well on a PDA, because you
have a smaller screen and no mouse with three buttons and so on.
You should use downscaled applications, that take better care
for CPU and RAM ressources. They provide a better usability on

On the PDA itself, you can try zgcc , which was actually made for
the Zaurus, but maybe it works on the ipaq, too. It has all you need
to build and compile Qt/Embedded applications directly on your PDA,
without any PC.
On the PC side, you can download Qt/Embedded for free. It comes with
a kind of an 'emulator' (not really, but it looks like one), called
"Q virtual frame buffer" (qvfb) that allows you to develop your
application on the PC.
later, you can cross-compile it for ARM and build and IPK.
Setting up a cross compiler could be very annoying. I've never
made it myselft, but I found good precompiled cross compiler
environments on the net (, ) and they fit my needs perfectly.
I placed some links at the end of my posting.
