[Seaside] Comparing Comet Implementations

Hi Guys - I've been having a bit of fun with the comet implementation in Seaside
(using the basics from the Seaside tutorial and using JQuery instead).

One thing I notice in my little test app is that my page never finishes loading
(I can see this little loading spinner on my apps's tab in firefox) - which I am
assuming is the pusher script waiting for changes to be sent to it?

Anyway - I noticed that Hudson (the java based CI tool - that some of the
Smalltalk projects have now adopted for builds), must use a similar comet
functionality to display its console output of the build progress. 

Looking in firebug it looks like it keeps appending divs to its page to show you
console chunks, which is quite neat.

I mention this because its page doesn't show the reloading spinner for the page
- instead they have their own spinner embedded in the page.

So I'm wondering if there is another way to do Comet than how its done in the
Smalltalk package?
