Hi!  I'm the main author of Vertex.

As far as I know, there's nothing really similar to Vertex, especially 
not for Twisted.  I'm really glad you're looking at it though!  As 
you've noticed, it's got some bugs, and it needs maintenance.  However, 
to sustain maintenance there has to be some interest, and with bugs it's 
difficult to attract interest ;-).

Vertex is a very interesting proof of concept though, and a lot of work 
has gone into it; it wouldn't be a huge amount of work to turn it into 
something really robust (and awesome).  In any event, it would be a lot 
less work than doing it over from scratch :).

A few other users have reported issues with Windows.  Is it this?

Can you be a bit more specific?  Is there a traceback?  Is there an 
exception?  Please provide as much information as possible.  You may 
want to sign up for the divmod-dev list, which might be more appropriate 
for discussing Vertex.  On the other hand Twisted users might be 
interested in hearing about semi-transparent NAT traversal and federated
