I tend to agree that stuff like OpenShift falls into the cloud 
applications SIG. My only qualm with that is that it means that 
something like a quick-start or cartridge then kind of gets pushed out 
of the cloud application category. Maybe it doesn't have to and both 
classes of applications (both the PaaS and apps that run atop it) can 
live together in a single SIG in harmony but they seem to be different 
enough to be confusing.

Russian-doll cloud problems ;-)

This like xlcloud and mesos seem like they should be in the cloud SIG 
proper to me since they're solving problems that people who run 
applications on top of public/private clouds (think a ruby/python/node 
app) don't really have unless they're running at massive scale.
