I would. Unfortunately, 1.5.2 is still the default install with redhat
systems (which are quite alot). I'm using Twisted to write gtk network
applications (such as an irc / msn client), and it's very usefull that
people can use the default pytgtk/glade packages that come with their
distribution. Requiring that people upgrade to 2.1, along with pygtk, 
pyglade (and of course install Twisted on top of that) may prevent 
people from using my applications at all.

I wouldn't mind parts of twisted being 2.x only - I only use the 
protocol/tcp parts of Twisted at this moment.

With regards,
