One thing I didn't notice on the plan is that right now we have a lot of externals set up, some of which are also dependent on the Toolserver. Should we be converting these to git submodules? Or what?
Also, I added a comment on the page about giving all current commiters +2 since that wasn't explicitly stated, and drafted a list on the talk page of some things we should do/update after the migration (update docs, update nightlies source, etc)
