software load balancing

[Chad M Stewart]

I worked with a customer once that had a software based load  
balancing solution.  I liked the way it worked.  While I was working  
on the box if I was going to take the service down for maintenance I  
could tell the local agent and the box was removed from the pool of  
servers.

Anyone know of something like this that runs on OpenBSD?  The master  
controller part on openbsd would be great, with agents for various  
other operating systems as well.  carp/pfsync is great, but I'm  
thinking of a times when the application that needs to be load  
balanced won't run on openbsd, say only on Solaris.


Thanks,
Chad
