I should have mentioned that I've tried setting up bridging and taptap without success when using the wireless interface. I use it on my desktop PCs (wired ethernet and Ubuntu) where it works OK though it's very cumbersome to start up and shut down.
I thought the main advantage of a bridge was the fact that it lets the host and the emulated machine speak directly to one another via network packets, and that's a feature I don't really need in this case. Using the serial port emulation with a VT100 emulation over a tcp/ip socket is adequate and works well. On the desktop machines, the taptap module seems to have a tendency to "hang" on shutdown, even though the SIMH emulation has been closed down normally. The unreleased bridge port will keep the entire host from shutting down and requires a forced power off, which isn't very nice.
