Not really :) and I am not the OP. This article [1] provides a very good overview of the repository organization Google has and the reasons behind it.

I think the reason that this works for well Google is the amount of test automation that is in place which seems to be very good at flagging any errors due to dependency changes before it gets deployed. Not sure how many organizations have invested and have an automated test infrastructure like Google has built.
