RFC: svn for make fetch

[Eitan Adler]

Alright - I updated the wiki page to summarize the thread so far.
I'd appreciate if people could comment on the "spec" part
specifically. I'd like to see that section become much more specific
(so that I could use it to unambiguously write something based off of
it)

I'm holding off on writing any new implementations at the moment to
see where things head in terms of how things should be done.
