yep - especially when a certain vendor is always using the same port :-(

;-) a name check will always get my attention... okay..not quite 'grumbly'
but if everyone used such a a method then we'd have to look at loads from
each end site and email them about what order they should do their 
National Proxies in... at least with some reasonable client balance
thet architecture might get used fairly and evenly. heck...maybe someday
Status-Server will find its way a little more fully into the system
and then if NRPS get busy they can just dynamically tell clients
tthat they arent well and bother another box :-)

ouch. that should already be inherent within the EAP balance?

doesnt this patch just make the 'balance' system become exactly
the same as the fail-over system? ie, find a live one and stick with it
for all times...
