Yes.  When I got my account originally (4 months ago or so) I was 
under the impression that multi-link worked, but when I asked them 
directly about it failing they said that it's not currently supported.

A friend of mine is having a lot of success with multi-link on 
Demon's test equipment, so it may become available RSN - who knows :)
