So, if I understand correctly, we've got a computer (more specifically a laptop?) and a Droid, but no connection to the internet proper (ie no cable/dsl modem or router/wireless access point like most common household wifi setups)...? Am I understanding?
If so, my next question would be this: the laptop probably has built in wifi support (or perhaps you have a USB/PCMCIA wireless adaptor), so that if you *did* have a router/wap you *could* connect to the internet?
If so, couldn't an ad-hoc wifi network be setup between the laptop and Droid?
Hope I understood your parameters.
If not, or if things are more complicated, maybe you could buy a bluetooth adapter for the laptop/computer/whatever and find something that works that way?
I'd love to see if you can get something working.
