I don't think you need special lb hardware. Just use two machines (or
even two TC instances on the same machine) and have one redirect users
to the other. A single switch (the redirect) is all you require. Adding
load balancing into the equation will just introduce new problems.

Also, you're not trying to balance load. You're trying to send users in
different states to different places. Why not skip the extra step of
determining the state on the fly and just send the user to another
server (permanently)?
