We do this and wound up using 2 virtual routers with BGP to handle failover. We aren't doing load balancing, just redundant failover, though.

You could replace OSPF with BGP in that article and do load balancing. Might have to run on the same virtual router though. I've read the dual virtual router with BGP article as well and yes, this is an primary/failover VPN solution. Remember, you must enable ECMP and if using iBGP there are a few more hoops to jump through.
