Maybe. I've prioritised outgoing VoIP traffic on my router and find it
still works fine even when the buggers are STMing me as long as I don't
have any torrents going at the same time.
STM is a stupid idea. VM are just shooting themselves in the foot. I
only know of it's existence from reading VM's support newsgroups. Most
of their customers are probably unaware of the practice and so have the
impression that their VM broadband connection sucks much more than it
actually does. They then complain about this to everyone and bad news
spreads better than good
