Twisted is a much lower level solution than parallel python or
processing. Are you thinking about using Twisted directly or just
using it through IPython (ipython1 is not in trunk IPython). Unless
you really want the treading API that processing provides, I think
IPython is by far the best solution [I fully acknowledge my bias here]
for high-level parallelism.

I don't think we really discussed this on the mailing list, it was
probably private discussion between Fernando and myself. We went with
1) we didn't want to reinvent Twisted
2) we really need what Twisted provides, so the temptation to reinvent
it was great.
3) Twisted has the right abstractions that force you to write correct
an robust networking code. Of course you can do this without Twisted,
but you are going to work much harder and probably get it wrong in
subtle ways that are hard to figure out.
We have been extremely happy about going with Twisted - it is our secret sauce.
Are there any specific questions you have about Twisted?
