Hi Youcef,

Yes, we recognize the efforts of the existing Atlas contributors and I
definitely want to make sure the atlas folks play a key role in figuring
out how LBaaS works in OpenStack moving forward.  I get asked about LBaaS
fairly often, and I've always been a bit fuzzy on what to do about Atlas
for two reasons: 1) L4-L7 services are generally within the scope of what
Quantum expects to cover and 2) its java-based, and core projects like
Quantum are required to use python.  I'm hoping the efforts of Eugene and
others is a first step in helping move existing Atlas functionality and
team members into a more permanent home as part of a core OpenStack
project.  As I mentioned, my feeling is that LBaaS makes sense as a fairly
independent sub-component of the Quantum project, but ultimately, such
questions are determined by the PPB.

Dan
