We we do it exactly this way using a multi platform Qt solution. Works
dead reliable. If you don't need the graphical front-end, maybe "expect"
is the tool for you. A sample script has been posted to this list before.

When the application loaded by Redboot is up and running, we provide an
alternative way to update. You can connect with a client via network and
then upload an image that is flashed as it comes in. If something goes
wrong there you still have the opportunity to repair the system via Reboot.
Regards,
Dirk
