Thanks dp,

Ok - makes sense.

>> Is Twisted + Woven ready for production web apps?
>>  - Is Woven API stable?

Is there anyone doing XSLT in Twisted? Any xml comparison to say 4suite?

I was thinking in comparison to using Apache loadbalancing - mod_proxy?

How would you compare getting web programmers up to speed on twisted vs with
.Net, webware, and zope.

My impression with zope seems to have everything, but also a mess.

Developed using .Net - pretty easy, but buggy.

Webware, seems simple and has a similar clean style to twisted. But, twisted
seems more capable / flexible.
