Ajax based multiserver MySql admin tool?

I was wondering if anyone is using an AJAX based tool to manage their MySql servers?

With about 4 sites hosted at different hosting companies, I need something that can manage all of them from the same interface and ideally should run from my browser, not as a standalone product.

So far I found only one product (made by NovaQuantum) that does something like that, but I would like to compare it with other similar tools:)

phpMyAdmin can do this; it has the ability to handle any number of servers.

Yes, but you need to open different windows for each servers and you cannot copy/paste WHOLE databases/tables between them:)
