A few days ago, I *did* post that the SUP server had been reconfigured 
... two or three new sets were added, and the server conviguration was 
placed under revision control.

However, since then, I've been getting an awful lot of "time out" 
messages from folks.  These timeouts seem to correspond to the following 
conditions on the SUP server:

netstat -f inet | grep sup

I have a hard time believing that this is an artifact of adding a few 
sets to the SUP collection.

I simply haven't had time to debug this particular problem further; my 
weekend was quite busy helping a friend move to a new house and getting 
the network insatlled at a VR conference my Real Employer is co-sponsoring.

In the mean time, however, I've restarted the SUP server, and I see now 
that folks are getting through.
