Damn, I almost bought the Linksys WET11, too, but I was annoyed with
them.

I had thought about this.  I can scrounge up enough parts to put a P133
there.  But -- this is in my living room.  Right by the front door.  I
don't like the idea of having a computer, Dsl modem, AP, and all
associated wires right by the front door, next to my fireplace.  This
house is 50 years old -- only 2 phone jacks, 1 in living room, 1 in
family room.  Needless to say, when they built it they did not string
any CAT5 ...

So do you think it is too much to ask of the point-to-multipoint bridging
mode to be able to not only bridge the zoom to each leg, but each leg to
the other?  It seems reasonale to me, but I am not a networking guru.
