First you appear to be abusing 169.254.x.x. Probably time to deploy
DHCP, and allocate a random portion of 10.x.x.x to those boxes currently
using 169.254.x.x.

Routing, and load balancing across multiple vendors for outbound traffic
is covered in LARTC section 4.2, and 4.2.2.

Inbound traffic is more complex.

The cheap and tacky solution is allocate 2 IP addresses to each server
(either directly, or via a NAT/PAT device), and use the normal TCP
connectivity behaviour to try another address if the first fails.
Doesn't load balance well, doesn't fail-over quickly, but maybe good enough.

The right way is to do it at the routing level, but that may require
changing arrangements for the lines to use BGP, renumbering etc.
