the balanced servers, just one server has to be in control with a monitoring program. Master node
receives request for connection, checks # of concurrent connections to all avail. servers, request
gets assigned to server with least # of connections. I leave the details of how to do it to you.
I'm not the programmer here.

than I could. The setup was genius. Way more complicated than balancing ltsp connections need to
be, but very informative none the less.

what about something like the intel eepro + series that can setup
teaming via the e100 mod and their management software? I havent
tested that feature yet but plan to in the future..
