MVP component selection: calendar app

@getsubrosa/owners Current proposal (from @ryankanno) is owncloud, since it covers a lot of ground in one app. Thoughts?

Does owncloud work usefully on small systems (small virtual machine, say <=256MB ram) for a few people (~5)?

[ryankanno]

@nh-github Probably not with those specs. Personally, I think we should probably be targeting Amazon or (insert another cloud provider) - seems reasonable since most people won't have their own machines to run this on.
