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?
