| I update my blog and I want it to be known instantly. Google does not provide it yet.| If your blog supports providing a dynamic sitemap, and notifying google that the sitemap has been updated, it basically does.

On your other points, I'd be pretty surprised if you couldn't provide a twitter-type service, at twitter-type message volumes, using e-mail as the hidden back-end. I don't think hundreds of local recipients would be that big of an issue, especially at twitter message rates/volumes. I'd be willing to bet it could be done pretty easily with a small number of decent servers. Then again, it could be that the Twitter folks know something I don't. Or they're just too emotionally invested in their existing back-end. No idea.
