Re: Git for games working group

Perhaps git-global-graph is a decent name. GGG? G3? :). The structure
right now in my head looks a bit like:

Global Graph:
     client - post-commit git hooks to push changes up to the GG
     git server - just the standard git server configuration
     query server - replies with information about the current state of the GG

Locks Pre-Commit:
     client - pre-commit hook that makes requests to the GG query server

For cross-platform compatibility, the Global Graph client and the
Locks/Conflicts client are the pieces that need to be use-able on all
platforms. My goal is to keep these pieces as simple as possible. I'd
like to at least start prototyping these in Rust, hopefully in a way
that can either be easily ported or easily re-implemented in C later
on, once things are feature-frozen.

For LFS, The main points of integration with I see are:
    -- bundling of packages (optionally install this package with a
normal LFS installation)
    -- `git lfs locks` integration. ie. integration with the read-only
control of LFS

If we push more of the functionality into the gg query server, the
integration with `lfs locks` could be simple enough to be a couple of
web requests. That might help avoid integration issues.

What's the main reason for this? Build system complexity?
