What would you be connecting to the empeg for? Data transfer would be SLOW.

It has a GPS receiver attached. I could do APRS gatewaying.

Best you could do is to maybe connect your cell phone to a PDA or notebook and perhaps do something that way. I don't think its possible for phones to do what you want to on their own

Well, yes, the point was, I don't want to use a laptop, I want to use some purpose-built computer for it. When I hook the phone to the laptop, I make the laptop dial, and do PPP, and it works. I want to disintermediate the laptop, and use something whose purpose is just "talk PPP on a serial port and ethernet on a 10bT"
