You could employ traffic shaping on the network, that's what we do at 
work. It's quite easy to nest HTB classes to achieve a situation 
where multiple customers have their own traffic allocation/limit and 
within that, their traffic is shaped & prioritised (eg smtp is lower 
priority than http etc). If there's a lot of customers, then you'd 
probably want to automate the rule build, and you might run into 
problems fitting all the classes into 256 identifiers.
You could do this on the Dom0, but I suspect that might be quite 
tricky. We do it on the boundary router - which is closest to the 
bottleneck.
