It's basically a web app development tool. The big benefit is that
you can use it to very quickly throw this sort of app together (you
can just point it at a database, tell it what forms you want, and
it'll draft a web app for you), which is why I thought you may be
interested in it. It sets up a local server automatically (based on
Python's httpserver, like Quioxte, CherryPy, etc.) so that users can
run and test the web app locally, and then there's a set of server
components to install to a server. So it'd be similar to your
situation now where you'd use py2app/py2exe to bundle the server
components and your web app together.
Of course, if you've already got a static web-app built that you just
want to be able to run on machines with no (or slow) internet access,
then there's probably no need to switch tools. I haven't done a bake-
off of the various httpserver-based web servers out there, so I can't
say for sure which one best deals with the various quirks in various
browsers. (I know that ActiveGrid's server handles the IE post bug
fine where it sends an extra two byte line feed sometimes.)

At present at least, there's no way to do this using wxMozilla.
There're probably ways to do this using some Mozilla hacks, but I
doubt they'd be supported. And considering that even Mozilla's
primary embedding interface is still (as of 1.7.x) considered a
'private' interface subject to change, I'm not sure you could even
rely on the hack to continue working in the future. The server route
is a bit of a pain but is probably the more sustainable solution in
the long run.
