Cisco SA520 VPN (IPSEC) Backup Route over T1

Straight forward setup. We used to have two locations and connected by T1 using a static route.

Jump forward to 2011 broadband comes into our neighbourhood and VPN  promises speeds which our poor T1 desperately lacks.

VPN testing works between buildings using SA520's from Cisco (basic testing done)

We would like to keep the T1 in case our cable goes out and re-route it back the old way.

I believe a static route with a high metric is all it needs but I am worried that there might be confusion having one static route pointing to the 0 and 2 subnets while the VPN says something else.

Obviously I can not do any testing until this weekend but I would like to have my doubts eliminated before coming in this weekend.

Or should I just enable RIP and pray it to work? We only own 2 cisco routers (the SA520's) the rest is dumb switches.

I would configure a GRE tunnel over the broadband conenction to the remote site and use OSPF to
dynamically choose the correct path . Use the bandwidth command on the T-1 interface and the tunnel interface to ensure proper route preference, the higher bandwidth link is preferred if configured.
