Suit Up! is an Internet television program out of Australia that's almost ready. The show is in "fine fine editing" stage and given that the most recent blog posts deal with issues with the end credits, it sounds pretty close to me.
Shows made specifically for Internet distribution aren't exactly common these days, but they're gaining steam. I'm not speaking of the Rocketbooms and Ask a Ninjas of the world, rather the full-length serieses (serieses?) that are able to give any main stream tv show a run for its money.
Something to be Desired is another Internet-based show that's doing very well.
These series surpass videocasting in that they're highly produced and have a much longer train of thought behind them. However, I'm still encouraged to see them becoming more popular because that bodes well for the while self-published ideal.
