Of course.  Grumpy as we are, we're preparing for the 3.0 migration, and 
have been for a while.  There are tickets open in the tracker, a 
buildslave reporting 2.6's -3 warnings, and soon, apparently, a 
buildslave that will attempt to run the tests with 3.0, although getting 
anything but a traceback bootstrapping the testing tool is a ways off.

My attitude in every public statement I've ever made about 3.0 has been 
that there is too much migration work for our tiny team to do, but we 
are very open to getting help from the community.

This isn't really the way our development process works on Twisted - we 
don't have enough developers to support more than one line of 
development.  Modules and subsystems can be patched individually, and 
the whole idea with 2to3 is that source changes should remain compatible 
with 2.6 (and appropriate level of swaddling can paper over library 
changes back to 2.3) so those fixes can just go into trunk, right?

Nevertheless the sentiment is the same.  If someone desperately 
interested in getting Twisted to work on 3.0, there would be lots of 
work for them to do and a clear place for them to go do it.
