Is it considered difficult, and can the SCM do anything about it at
all?

I think that very much depends on the scm used in the upstream
project.

See above.

You need to pick a distributed or two-way scm for that, e.g. git or
mercurial.

See above. Distributed/symmetric vcs allow for pushing/pulling from
both sides (provided permissions are properly set).

Personally I favour mercurial and git, and I think they are both that
much alike that I would leave it to the koji developers to pick one,
as they will be the ones that will go through the pain of
implementation, and they should pick what will really be implementable
in this short time frame.

(ideally the vcs support in koji would become modular with an api so
anyone can add his favourite vcs to it)
