Feedback Appreciated: Sutro Software

Fellow Hackers, I'm looking for feedback on my startup: Sutro Software.

http://sutrosoftware.com

If I may, one request and two disclaimers...

Request: I would appreciate it if you would not register to use my product unless you actually use Vignette Portal. The screenshots and videos should give you a good idea of what the product does if you're interested.

Disclaimer #1: If you use Firefox 3 on the Mac, the Javascript animations will be slow.

Disclaimer #2: My site is not set up to scale well at the moment so if there turns out to be some interest on HN it may fall over.

Thank you very much in advance for any time you spend and any feedback you provide.
