I'm sorry that we (Komodo team) missed it, but I did not see such a
message on the Komodo mailing list.

Just to detail how Komodo works, as there seems to be some confusion on
* Komodo is based on top of Mozilla (like Firefox, Thunderbird,
Democracy, etc... )
* Komodo includes PyXPCOM (XPCOM bindings to the Python language), which
objects inside an embedded Python.
services are written using Python code.
To enable the use of Python from within the Mozilla framework you'll
need to build mozilla with the python xpcom extension enabled.
For a simple overview of building and making use of PyXPCOM, see these

I would not recommend this for a small project, as there are many build
related issues (especially since you'll need to build a separate
Mozilla/XulRunner application for every platform you support) and a
steeper learning curve for getting an application like this to work,
packaged and installable.
Yes, it is definitely a lot easier to build the UI using XUL and it does
look consistently better across multiple platforms.
Using Mozilla you'll gain access to a wealth of components with which
you can take advantage of within your application.
Note also that for the Firefox 3 codebase, it is expected that Python
you'll be able to write Python code that accesses and manipulates the
user interface and the DOM.
