I've been puzzling about the problem that BlogTorrant solves for quite a while.
Namely — how can I make it easy to put BitTorrant versions of big files (like my Sex and Podcasting podcasts) up on my sites.
These sites of mine are built on Xoops, a very nifty, very flexible open-source content management system that can do all kinda cool stuff. But blogging isn't it's strong suit — not terrible, but it's a little clunky at things like track-backs, RSS, etc.
I solved the “how do I do enclosures?” problem by using FeedBurner to generate the RSS feeds that you're seeing — one of the nice things about that system is way it auto-magically does all the enclosure stuff for podcasting.
This BlogTorrant gizmo looks like it might be the add-on that will make it easy to do BitTorrants in the Xoops environment — I will do some tinkering and update this post with a cookbook if things work out.
