If you can make the auto update part work then super more power to ya!
However, you should include an option at compile time for the installer of the module to decline auto updates.
I'm sure there will be people who don't want it or can't use it.

On the file name format front: Have you asked them if they could standardize their naming? Perhaps they just never considered that someone would want to automate the process? It's a longshot, but might be amusing to hear what they say.
