If you haven't seen this before, check out Broadband Hamnet. It's a network of highly configurable networks (referred to as a MESH network) that hams can use. It's particularly useful in an EmComm type scenario, but is useful for all kinds of other connectivity and communications scenarios.
You can find more information at www.broadband-hamnet.org
Come join me. We need more in the Toledo, Ohio area - I'm the only one so far.
