The problem with collaborating online with Ardour is that the files that are generated when you record an auditory product are very LARGE. For example, if you decide to create a zipped tarball (a method to build a single file from a group of directories/files and then compress or "zip" that file to save space) a simple 5 minute song with just percussion and bass guitar could take up somewhere between '''90 Mb to 120 Mb of hard disk space'''... Imagine posting that file on the cloud, or making that file available on a distribution server!
