Hi,

Here is a version of PyCrust I hooked up that uses
Manhole. I'm trying to figure out if there's a way to
easily mix together some free tools to make Twisted
development on Windows easier. Comments wanted.

Hi All

I am new to Twisted networks.I read its documentation that it is a network over which we can build network applications like chat server.
I have queries regarding , Twisted Word chat server , written in python.
I just know that it is available under free BSD license.
I want to know that is it available as a free download.Can I download the server and a compatible client ? 
are the APIs of the server available?
How many simlutaneuos users does it support.
Does it supports group chat and multilanguage chatting.

Thanks

Hi,

I am contemplating running XML-RPC over SSL (basically for site to 
site process communication over the internet). Has anyone got any 
example code that would point me in the right direction (or just some 
clues :-) )

cheers

Twisted Words provides a server accessible via IRC and PB. Any IRC client should be able to connect to it. The PB interface allows for easy programmatic access. It does support groups. It uses unicode internally, and transcodes messages received/delivered via IRC. The PB interface is just natively unicode.

It is written in a way intended to make it easy to plug in new access mechanisms. For example, one such plugin that has already been written is a Nevow LivePage-based web interface.
