certain server and keep that mapping throughout the entire session.
I'd also like to have some means of detecting a server that goes down
and yank it from the load balancing pool. I do understand I may have
to write some code on that side.

pf and sticky rdr.

Use a shell script that pings the hosts on the backend, to
insert/remove them from a persistent table.

Have a look at: http://www.countersiege.com/doc/pfsync-carp/#big for one
idea. All requirements (carp, pf and pfsync) are available in FreeBSD as
well.
