Well, that's not necessarily true.  Yes, of course you're going to add 
some latency, but it doesn't have to be too much.  It all depends on how 
the US data center is peered.  If it's peered with primarily Tier 1 
backbones that privately haul trans-Atlantic traffic and go back to 
LINX, Redbus, etc. in London, you're pretty well off.

That said, of course, there is additional latency.  If by "telephony 
applications" you mean media handling (and no way to release it), then 
you probably don't want to be in the US serving a UK customer base.  If 
it's another kind of telephony application, it might work great.

There are several calling card vendors I deal with that send their media 
to termination providers in Western Europe from here in the US and don't 
seem to get any complaints.

Well, of course.  It's pretty much the same here, with the difference 
that it is more typical to just charge for another block of amps as an 
overage rather than bill obscene amounts per amp.  It depends on the 
data center, though.
