Do you have any questions for the Elastra CEO?

It looks like in the near future I'll have a chance to interview the Elastra CEO. Elastra provides standard
databases--MySQL, EnterpriseDB and PostgreSQL-- on top of EC2 and S3. They are selling aggressive pricing, expandable and contactable database resource usage in response to demand, and a simple management and operations interface to well known databases deployed in a cloud. Elastra could be an important option for developers looking for a more traditional cloudy database.

I was wondering if you guys had any suggestions for questions you would like answered? What would you like to know about their service? What are you looking for in a cloudy database? What would stop you from adopting it or what would make you decide to adopt it? Any ideas you have would help a lot and will probably be better than anything I have.
