I'll echo what Kevin said on that thread.  If you're interested in
building it, I'm interested in having it!

We're still learning how to do our feature proposal process as a
community, but generally we are following the process here:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Adding+new+features+and+design+documents

If we have a consensus around adding support for LXC, then the next
step would be to propose it via a functional spec.  Purely from a
release planning point of view, I'd suggest that you add the spec as a
child page of our "uncommitted" design page:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Design+Documents+Not+Committed+to+a+Release

Also one other thing to note: the community has two major refactoring
merge activities that we expect to happen this week / early next week
(first, the api_refactoring branch, then the javelin branch). You
should be aware of this, but I doubt it would impact the design much.

If either of you decide to take this on (and perhaps collaboration
would be in order), please do share your thoughts, questions, concerns
with the list!  We're happy to help with the architecture and our
community processes.
