Woohoo!

I had thought about this, but I'm pretty strapped for time as my startup 
is self funded.  Plus, it's not exactly like I can just walk into your 
SVN repository and start hacking. ;-)

On the other hand, for all the free mileage I've gotten out of Twisted I 
do owe you guys a certain debt!  Perhaps I could help out on NewPB, 
especially since I could really use the Slicer code Brian was talking 
about.  However, I'm in a bit of an awkward spot to do so right now 
though, as I'm not yet using Twisted 2.0 and my project isn't at a good 
point to upgrade libaries.  Still, I've got to upgrade sometime...

Is there a good place to read more about NewPB?  Or is it just a matter 
of searching the maillist archives and SVN repository?
