You've really only got a few options available:
(1) Proxy ARP
(2) ICMP Redirects
(3) ICMP Router Discovery Protocol
(4) Run a routing protocol on the workstations
(5) Hot Standby Router Protocol
Of these, (4) is probably the least desirable, (3) is the least widely
supported and (5), as you said, is out of the question. So, you really don't
have a lot of choice, as I see it. If you want it to be dynamic, there is a
limited number of things you can do, and running a routing protocol on the
workstations, though viable, is probably not desirable as that would almost
certainly involve running RIP v1. As I see it, you're down to choosing
between Proxy ARP and ICMP Redirects, though neither one is really
desirable. HSRP would be a perfect fit, were it supported. So there you have
it.
