@pratik I like it. I've been thinking of doing something like that. I like the way Dave Winer does it but I don't want to host on his service (for a number of reasons, none of them having to do with him personally). Do you happen to have a link to the code, or some keywords I can use to search for it on the forum? Thanks!

I suspect it may be beyond my skills to implement this, but it's worth looking into.
