Then the contents can go directly from RAM (pharo) to RAM (repo server or git) without going through slow disk filesystem. I should say that there's a poor implementation ration for Squeak; poor because it uses the C binding. The right way is to go directly over sockets. This provides efficiency, flexibility and some degree of concurrency; all of which are lacking when programming against the C binding. One could do so much with this other than merely an elegant interface to a vcs. As my friend David Simmons points out, the major benefit of Docker is being able to configure (and hence version) an os virtual machine through the host file system, instead of having to start up the os virtual machine and configure within it and its own file system. A FUSE interface for Pharo/Squeak/Cuis (I'm going to start calling this triad Cusp, Cuis union Squeak & Pharo) would allow non-Smalltalker dev ops people to configure (or monitor, or...) a Cusp image as if it were done familiar native tool. > > Regards ..

DVCS integration via users pace file system
