Yes, that was the conclusion I'd come to.

The ADSL wasn't really the issue - I just used it to illustrate the
scenario. This was of purely academic interest at the moment. I do like
the idea of getting fast data paths via bonding multiple interfaces
though. Would be a great way of getting gigabit speeds with cheap
hardware. A couple of quad port NIC's would do wonders :-).
