[Trac] Integrating Trac with existing Wiki tool

[Ondrej Krajicek]

Hello fellow Trac users,

we have recently deployed Trac to aid our development efforts. However, we
have a well established Wiki tool (TWiki) with lots of topics. Is there any
way how to integrate external Wiki tool with Trac? I thought of something
simple like rewriting the logic which generates the wiki hyperlinks/url to
target different Wiki (the TWiki and Trac Wiki URL contents are almost
identical). 

So, instead of generating a hyperlink: 
https://<hostname>/trac/wiki/ActiveDirectory (when I use the ActiveDirectory
wikiword), the following link will be generated:
https://<different-hostname>/twiki/view/ActiveDirectory (the WikiWord is the
same).

But I am not yet proficient enough with the Trac source code (yes, I know
Python). Can anyone suggest how to accomplish this in the most elegant way?

Thanks in advance,

Ondrej
