When will tasteful open to the public?
I have no idea. tasteful is a very real product, however, and is open source - you can view the code here and track my progress. The vast majority of the stuff that is not yet available on the public website is still in development locally, and will be committed to the repository once tasteful is closer to launch. Contributions are greatly appreciated, however, and you will be rewarded accordingly with a 'Contributor' badge.
