Conferences On the Web

Edd Dumbill and Dave Beckett have set up a Chump bot to allow community coverage of WWW2003. This is an excellent idea, and will sure to be packed full of useful and interesting links.
However one thing I’d like to see conference organisers do more of is to make the presentations available over the web as streaming video, or even just audio. While a certain amount can be gleaned from reading slides published after the fact, there’s nothing like seeing a presentation for yourself. And it doesn’t seem like the technology is that hard or expensive to actually deploy.
I’d certainly pay money for a service like this as there are a vast number of conferences which I’d love to attend but can’t (usually for cost of travel reasons).
