[AG-TECH] Problem with the beacon?

I rebuilt this using a larger maxReportPacketSize a couple of weeks ago 
(mailed the new code to our buddy ChrisG) because the nlanr-beacon 
wouldn't start and our nodes started appearing again.  That solved the 
problem of our nodes not being seen at all in the "tree".  Its sort of 
the situation where the last one (more than 8192 bytes of information) 
loses - but the early arrivals were still seen correctly. 

There's something strange going on - I rebooted the vrvs-ag & a couple 
of the cakebox nodes & they magically reappeared in the beacon page.  I 
changed nothing else, just restarted, yesterday, (by rebooting) the 
nlanr-beacon process.

Has anyone heard anything more from the NLANR guys?
