hmmmmm need some help peoples... (no change here then!)

At the moment i read the firmware versions and return something like PR1.1 - or PR1.1.1 ....
Quite easy to do at the moment... but i will hit a snag when new firmware versions come out, as i will have to update the code, then wait the 10+ days to get it out to people.... Not much help...

A few way rounds i can think of are....
Listing the versions on my website and parsing it directly from there (not good if people dont have or want to use the internet.)

or

Giving the user the ability to download a text file with them listed in, and update when they want.

Are there any other ways people can think off? or any previous good examples?
