Perhaps there is some aspect of your question that I do not understand. But the 2811 can certainly do VPN over the Internet (assuming that it has the right feature set to support VPN - which yours does if it is already running IPSec with ppp link.

I have done IPSec VPN over the Internet with 2800 series routers and they work very well for it.

You can have multiple crypto maps configured with associated ISAKMP references. As long as you configure these correctly you shouldn't have a problem.
