@mschnell:
First of all, please shift your paradigm regarding web programming. No matter how good is ExtJS, ExtPascal and ExtPToolkit, you still NEED to learn the basic concept of web programming, Ajax (including server push Ajax aka comet as you seem to need it), HTTP communication, CGI and FCGI mechanism. If you still lack of them, we can't help you much.
And, as Phil said, it's better to continue this discussion on ExtPascal group as most of ExtPascal people are there. Only some of them are watching this forum.
Thanks.
