Hi, The new protocol i mean is the network transfer protocol, like rsync. Is the word "dumb protocol" you mean is the network transfer protocol ? But seem if i just implement a new protocol using jgit but not in C (integrate with git core code), it may not worth because more of the client using git core command line tool as git client.
