        Could you name some your top instances of this?

        One in particular i'm thinking of is where i have an antenna shooting into a coffee house down the street, and want to put an openap in there, but have my dhcp server in my apartment. So forwarding dhcp requests from openap to smc(prism2 card) card in pc sitting by window is what i desire. I have set up an openap and am getting familiar with what it can/can't do. Possibly i could forward the request via routing foo or the linux regular ethernet bridging but then the only device i'm going to have is the prism card in the openap so probably i'm stuck with WDS 802.11 foo, but still figuring.

        Also i've been groking the bridge-utils in openap and Lennert Buytenhek stuff and spanning tree protocol of ethernet bridging and what not, and i've been wodering what the performance of lots of bridged openap's (hostap's) would be. So if there are a lot of intances where routing isn't possible that performance would be even more important.

        Also i'm wondering if something of the ablity to broadcast to all machines on the bridged networks would be usefull, or just dealing with things at a lower layer, but then that's partly what tcp/ip was invented for(to make routing easier, route networks not individual addresses) and i guess ipv6 solves everything anyway. But i am really interested in situations where routing ins't possible.
