Load balancing two T1s to the same ISP can be done reuqesting that the ISP terminate the 2nd T1 on the same router as the first T1.
You would configuring a loopback interface on your end and finding out what the loopbackis on the
you then configure a default route that points to the ISP looback address
ip route 0.0.0.0 0.0.0.0 ip route 255.255.255.255 ip route 255.255.255.255
You ISP would implement similiar
router to router VPNs are usually GRE tunnels encypted using IPSEC.
so this traffic cn be load balanced using the method described above.

We have recently aquired a company in another state and I have been assigned the task of connecting the 2 locations. We currently have one T1 to the Internet running thru a 1720 router. There is no routing being done except for the default route out. The router has room for 2 WIC's but only one slot is being used. I do have an extra WIC for the empty slot. We are currently using a high percentage of our bandwidth during business hours (~
60%) and have ordered another T1 due to be delivered in about 3 weeks.How do I best load balance the 2 circuits assuming that we will be using a firewall-to-firewall VPN to connect the 2 locations? Will this router handle the task or do I need different hardware? Would it be better to setup a router-to-router VPN than using the firewall(SonicWall) method? Will there be any changes necessary on the ISP end or will all inbound traffic come in 1 interface?
I have many more questions but will leave it at that for now.
All help is appreciated.

If a VPN is serial interface to serial interface, (which it is isn't it) doing that would not allow for a router to router VPN. Is that correct?
I'm not sure what it would do to the VPN, but I have written a little HOWTO on doing per-packet load balancing across multiple T1's with Cisco routers. Might help.
