I've just finished writing a paper, which explains why Slashdot has made it back into my url history (procrastination has to be pretty bad to get me to slashdot, unless I'm looking for a laugh). But in this case Slashdot has really come up with the goods. FeedTree is an excellent idea. I'd had a few ideas about using Scribe for distributing RSS more efficiently but never got around to thinking it through fully.
FeedTree seems to have come up with a great idea and followed it through with a client which is basically transparent! It took me a bit to get it running at home because it wanted to connect to the net through my pocket pc, but once I got past that it seems to be working well. It could probably do with a bit more doco in places but I'm sure that'll come if it becomes popular.
Finally, if you want a good laugh go read the slashdot comments (as usual). FeedTree seems to have provided the most ill-informed comments I've ever read on slashdot, but perhaps that's just because I have a good understanding of Pastry thanks to my PhD. Now there's a new 2nd best Pastry based application behind G2:P2P (hmmm. I should get a link to the AusGrid paper up on that site, hey)
