The advantage in this case is as the mesh grows, additional gateways
along the edges can be added fairly quickly with only the core router
and the edge mesh router being updated, the rest of the routing
information flows back into the mesh and the load is automatically
balanced. (big handwave there) And no TCP resets.

Although keeping it on a central ISP is a downside, at least most
outages can be avoided (cat tripped over the router, a backhoe in one
part of town, etc)

I was looking over your deployment map. (http://www.sixxs.net/pops/)
You've come a ways... glad to see you are rolling out things in
america... I take it australia is hard to penetrate?

Just a BSD box I take it?
