You might be, but I don't think it would be a good idea. 256 kbps DSL line will be shared among all the branch routers and also that adds on to the vpn overhead.

Cheers,

Yes, just point your default routes at the tunnel IP.

You can create a lan2lan tunnel between a cisco pix and cisco router easily, if your routers are runing the Advanced Security IOS. At the remote sites just set a default route to the remote tunnel IP and you can have internet via VPN.  Of course you could just setup a VPN for private traffic and then let them use their local internet connection for internet traffic.  I expect the have one or else you wouldn't need to do VPN at all, becuase you would be going over a private frame, etc.

The only reason to route them through the vpn for internet is if you needed to have strict security and monitor all internet traffic from one device, like your pix, or pass it all through a proxy.  Sometimes secuirty is more important than speed. ;)  just depends on your buisness needs.
