Back to the original "available services" part of this thread, I've been
thinking about this as well. Maybe the group could consider a services
advertisement protocol like ZeroConf (Avahi in Linux, Bonjour in OSX)
with some modifications to minimize it's chattyness? Things like
stations should not beacon what services they offer more than once an
hour w/o being directly probed, etc.
