L2TPv3 is a great technology, and probably will be what you want. However,
it's really new and requires 12.3T, which I'm not prepared to run yet.
They are wrong about DLSw+, though. It will bridge anything in ethernet.
You have to use a BVI and not put an IP on the ethernet interface, but it
will work. I'm not sure why they would have told you that it doesn't. They
may not support this configuration, though. If you've got the means, use
L2TPv3. It's definitely the way to go.
