There are 5 weeks until Friday the 17th of March (correction from Ross's 
date), and I can tell you now that your main concerns (functioning 
relative to CVS with authentification, and functioning on Windows) are 
both non-issues.

Subversion has been developed from the start to work on Windows, and 
there are several windows clients available - a Subversion port of 
TortoiseCVS for the windows shell, a wxWindows front-end called 
RapidSVN, and of course the good old command line. It's also well 
integrated with IDEs like Eclipse.

And the mode we'll be using, svn+ssh, is a strict equivalent to the CVS 
ext: method with CVS_RSH=ssh. The same public keys that were sent to 
GNOME sysadmin way back when will work unchanged. I imagine that was 
part of the motivation for moving to SSH at the time, as well.

It's worth noting that from a user perspective, the mode of function and 
command set of Subversion were chosen to make things easier for people 
using CVS - the core command set is the same (co, ci, update, diff, 
status, log) - the things which change are branching & tagging, which 
are done with a simple copy of a directory (copies and moves are 
versioned) and we pick up some nice new features besides with versioned 
properties, atomic commits, and off-line diff and status (you can find 
out what you've done without querying the repository).

It's hardly a surprise that there are moves away from CVS. This has been 
discussed in length on ddl and gnome-hackers several times over the past 
few years, and now someone's gone and gotten it done.

All in all, I'd like to say yay.

Cheers,
Dave.
