	Yep, aegis runs suid. (needed to maintain security)  AFAIK that's not easy 
on Windows.

	I can't speak of the need for new version control for RT.

	But I personally note a difference between version control and 
process/configuration management.

	Aegis, for better or worse helps control the "how" of development and as 
such can add another layer of defense against stupid mistakes.  If 
configured it can prevent someone submitting a patch that doesn't build. It 
can require that a test case be submitted with the patch to prove the patch 
fixes the issue (must fail before patch and pass after patch). Things like 
this can easily be handled by the expertise of the developer for a while, 
but it does always seem to become increasingly difficult as things grow. 
And it can do other things like building a regression set, collecting 
metrics, etc. etc.

	There have been quite a few announcements of what I call "CVS 
second-generation" tools lately:


	But these are all addressed to take on CVS's shortcomings, none of them 
tackle some of the issues that aegis does.  They all look really cool, 
don't get me wrong.  But they aren't an apples for apples comparison with 

	Again, it all depends on the goals of your development project. I don't 
know what Jesse has in mind.

	I'll only say that there seem to be many candidates for the "CVS 
second-generation" above.  The competition for the spot should help deliver 
a great product.
