Is there a reason to believe that this ever happen?

I tried to use svn to maintain changes to the tinyos-2.x tree and it 
didn't work well at all. Merging was always such a big pain that I had to 
give up. My next attempt was with git and I'm still using it with great 
results. I was able to create diffs against the mainline and then easily 
merge with them.

The nice thing about git is is the fact that different people could 
maintain trees that have experimental features which, when mature, could 
be easy to integrate in the mainline. Things like safe tinyos or 
tosthreads are two example that could have been tested as experimental 
trees. There is no need for them right now but it could be for other 
things (for example the cc2420sim or the security support for cc2420).

One thing we could try is to start using git with a main tree maintain by 
Phil which he can publish to CVS the stable versions. I think this is 
possible because there is already some structure in the way development is 
done: David Moss is responsible with CC2420, Kevin Klues is responsible 
for tosthreads, John Regehr is responsible for safe tinyos and so on.

Are people interested in trying to do this? :-)
