Similar use case here. I would like to have code changes automatically propagated to a running application hosted in the cloud (in my case, Ruby on Rails, which picks up file changes on-the-fly in development mode). Something similar to lsyncd ( would be perfect. This gives me a desktop-like workflow but using scalable cloud resources instead of local processing power. 

Note that lsyncd typically uses rsync and ssh. OS X source for rsync is available at Not sure how hard this would be to port to iOS, but probably a better starting point than the original rsync source.
