Largely unrelated to the fact that they're getting more expensive than they ever used to be, we've been significantly reducing the need for them in WCF's COM+ integration features.

So it turned out that when the Beta 1 COM+ WCF Integration tool exposed a COM+ interface as the service
http://localhost/ServiceModelSamples/BE62FF5B-8B53-476B-A385-0F66043049F6.svc/C551FBA9-E3AA-4272-8C2A-84BD8D290AC7, it wasn't the most usefully named of things.

They were always editable to something simpler in config but, with the next build that you'll see, we'll start off with something much more approachable like http://localhost/ServiceModelSample/ServiceModelSample.esCalculator/ICalculator.

GUIDs will still live on when we generate a default namespace for the service since uniqueness in namespaces really is a good thing. Don't worry though - that one's for free!
