If you bridge the networks, they will be on the same IP range / subnet etc.

You would be able to come up with a solution based around the existing
wireless cards you have, however a much easier to establish and likely more
stable solution is a pair of Wireless Bridges (or AP's that can run in
bridge mode)

I'd reccomend either... (speeds are theoretical max assuming LOS between 2
sites)

A pair of DLink DWL-900AP+'s - 22mb/sec link
A pair of Linksys WET 11's - 11mb/sec link

I also believe the WAP54G's can work in bridge mode, this would give you a
theoretical connection speed of 54mb/sec.

(with all the above I would reccomend running a Vagi antenna off each unit)
