Hamilton,
I agree "post it" isn't probably the best name choice but I don't like private messaging either, as private messaging is closer to what Torben posted than to my idea. let's see if we come with a better choice of name, however, it's just the name, as I think the main goals of the package are more or less clear in the above messages.
Comet seems a good idea, if not for the first version of the package, for the second. Thanks a lot for the links, I have started recently digging for ajax info and will surely bookmark those (although the second one's server seems to be down), again thanks ;)
I have also in mind to take a look to Gustaf's work with chat as it is the reference in ajax server-browser communication in OpenACS, I also think both packages will benefit from the other one.
And yes, I will gladly appreciate if you send me the code as it will probably give me more time to focus on UI.
