The basic premise of the project is that
OpenWRT has a feed, NSLU2 has a feed, Moto fan club doesn't.
So, there's two parts one an ftp host one is a client that runs on the phone.
I might end up porting a command line client myself if I have time.

If you need an ftp to host the feed tell me and I'll get one.
If you can provide it free, 20$
but if you can get the feeds registered with debian, OE, gpe, etc; 60$
If you need feed admins since I guess it's a eventual need.
I'll volunteer but only for e680i, but I have no experience with others.
Usually the client is a command line program. 20$
but there sometimes is a gui interface to the command line version. 20$
If you set up the initial install to detect installed lib's and dependencies
since not all phones are the same, and some will need different libs.
This could be as simple as a ls of the ld_lib_path directories, 20$
but it could be as complex as a listing of groups of libs
such as all of curl shown as one package. 40$

Anyway happy coding,
