- Central repositories handle me working on a plane. Same thing.
- Central repositories handle your Chinese subsidiary being constrained to a slow and spotty pipe (they actually exported our tree with git-svn and used git on their end--this was at a NASDAQ company, it's not like anyone was cheaping out, it was the best available).
That you are willing to work around the deficiencies of centralization does not mean they are not deficient. Don't be ridiculous.
