unfortunate things which wasn't absolutely necessary for DSSS in the first
place (active probes are fine, no?) but which has come to be depended on for a
variety of functionality. Some of that could be changed, but PSP's dependence
is pretty deep...
Note that I've seen odd behavior from PSP clients
even with ``normal'' beacon intervals. Traces from the LAN side strongly
suggest that the client is missing packets which it has no reason to miss.
Hopefully that sniffer I ordered will shed some light on this as well...

other protocols (I never looked) but it can't pass arbitrary frames. It
associates as a single MAC address and frames to that MAC are the only one

such an approach.
