Skye O'Dell's dashboard

As a developer/designer, I have a lot of individual clients as well as projects that I have total control over. I will use my own ID for my own projects, and would like to recommend that each of my clients gets their own ID as requested, but I have a couple questions about that:

1. Can I use the same email address for all of the ID numbers if I am to control them?
2. Is there any thought to reseller capabilities?
3. If I do get multiple numbers on the same account, can I have a listing of those IDs and possibly the sites they belong with on my profile area within your site?

Thanks, this has been a GREAT idea and I look forward to continuing to use your product!
