MLPPP is why I was interested in the card. As it turns out, however, the
ISP is supplying a 28xx with 4 DSL WICs so it's moot anyway.

Yes, you need to be able to specify source/destination binding,
otherwise you get users complaining about banking websites &c not
working. This then means the load balancing isn't as optimal [because
you're balancing connections, not packets] but for the SMBs I'm thinking
of, a few broadbands + some kit is still way more cost effective than
BT's Excess Construction Charges estimate!

I can imagine odd performance problems if there's any significant
difference in latency across the two connections, to the site where the
VPN terminates.

The last guide I read to OER had a show-stopping restriction in that you
had to find one IP from each ISP that was only ever reachable from that
ISP in order for the link failure detection to work. Maybe it's time to
have another look at IOS.
ASA load balancing is a complete non-starter it would appear. Cisco
really need to pull something out of the hat for ASA2, because even the
lowliest Sonicwall can do outbound load balancing on four internet
connections [per connection, percentage based, spillover,
active/passive, you name it], doesn't have #user restrictions and costs
less to boot!
