3G Broadband open source gateway

Hello everyone, I'm just learning how to use this imedia distro on a minibox bought here at work, and I would like to propose a project, it might sound simple but I've been working on this for a couple of days and still haven't quite figure it out completely.

I want to create, as the title of this post said, a 3G-3.5G Broadband open source gateway, so basically it consist of setting the 3G modem as gateway doing a NAT assigning IPs to the hosts by configuring a DHCP server.

I'm working on a more formal project presentation in the mean time, I just wanted to see if anyone would like to help out with their knowledge If so, please just respond to this thread. I will divide the stuff to be done, or you can also help out just by being an adviser and helping out put out the fires we will find on the way.

I'm inspired to do so because I see a lot of people getting the 3G broadband Internet services here in Guatemala (my home country) but they usually want to share it between a couple of computers and current gateways are not available for sale here nor the US.

any comments, questions or ideas are welcome. Also, if anyone else has already done it.. let me know!
