perfsonar development work

Hi,
I think we need to be clear if we are talking about the current partial
implementation of the framework, or the design goals.

Right now static URL names are a good thing that will lead to stability,
and improved diagnostic capability.

As soon as we have a stable DLS deployed, then I think we need to make
a clean break with the idea of services at static URLs. We will need to
force applications to properly use the DLS, so that we can reap
the benefits of a dynamic architecture.
