for that you can pass "protocol=file" to make the git fetcher use the
"file" transport, see

http://ao2.it/en/blog/2010/05/27/neat-compilerun-cycle-git-and-openembedded

basically, in the .bb recipe, you can fetch from a local clone where
you do your normal work.

maybe you can pass "protocol=ssh" as well to the git fetcher as well,
but I haven't tried that, when you say "R/W mode" you are basically
saying "ssh transport" for git, right? Let us know if that works.
