what you are trying to do will not work. Typo3 and eZ publish 3 are two full blown CMSes with completely different architectures. Those cannot be integrated unless you want to code a completely new CMS which would probably take as long as coding either from the ground up.
If you want to code extensions to eZ publish, I am no expert at that but this could help: http://ez.no/developer/ez_publish_3/forum/developer/implementing_ez3_extensions
Also, if you want to integrate complete scripts, you could try this: http://ezwiki.blanko.info/index.php/3XHT_UsePHP
(Warning, quick & dirty, might not work with big scripts).
Other than that I'd say that integrating scripts is not the best idea in the first place as this usually creates a lot of overhead and makes things slow (two overheads instead of just one).
I will consider your opinion; but both systems argue that their system can be extended without any problem. In fact, this doesn't to be totally correct.
I am studying both systems and am trying to find a way to use use their competitive advantages.
as for the claim that the system can be extended, this means that they can be extended each using their proprietary extension systems. This means that you can extend the system by writing specific code that follows the (different) rules set forth by each system. It doesn't mean that you can automatically integrate pre-written stuff, especially if it is the core of a system. :-)
Anyway, good luck with your efforts.
Karsten P.S.: I haven't set up any site with Typo 3, yet. The advantages I see in Typo3, however are the number of pre-written extensions, i.e. ready-made applications and the already very comprehensive documentation / support. Both are only at the beginning for ez publish 3. Can't really comment on the strengths/weaknesses of the core system, although I like eZ publish better in that regard.
I have worked with Typo3 and while the extensions sure are impressive, it was even slower than the what I now consider beta template engine in ezpublish 3.0.
It sure has some nice features but overall, it's very bloated, it does a lot of weird stuff behind the scenes. And the admin interface is surely not suited for average users, only for people who know a bout web publishing already.
Oh and Sam, sorry about the stupid. I had been hacking away on something for quite some time without much success and was getting rather pissed about it (but note that I referred to the idea of integrating the two, not you as a person)...
Let both standalone and grab the content with a grabber. There is a possibility to integrate it with webgrab. We used it for an other cms and it works fine. http://phpcms.de/phpcms/webgrab.htm
It is already integrated in Typo3: http://typo3.org/index.php?id=1344
