perfsonar development work

[Maciej Glowiak <>]

Hi Anand and Nicolas,

We had a discussion with Anand (and Internet2 guys) about LS API that 
would be created. Such work is scheduled after the release perfSONAR 2.0 
process. I think I'll do it after (or in parallel to) performance and 
architectural changes which are the most important things.

Of course, requirements should be agreed before, next week for conf-call 
is fine for me.

Best regards.

Maciej
