Is that a general concern, or are there specific issues you are worried

How would this work? As a Boost developer how could I use the git repos for
my libraries if I can't write to them? How can I use the svn repo if I
can't read from it?

I have a fuzzy idea of what you are suggesting, and am interested, but
would need to hear specifics of how it could be made to work in practice.
