There are a number of cheap hosting services that offer MySQL databases, which can only be administered via PHPMyAdmin. No direct connections, no SSH access. I have dreamt of using HeidiSQL to access my data.
Would it be possible to add a new "Network type", something like "MySQL (via PHPMyAdmin)", which logs in and relays commands to an installation of PHPMyAdmin? Alternatively, it would be possible to write a custom proxy in PHP, which could probably offer a cleaner interface, and one that we control.
I'm ready to put some C++ skills at work here, and a lot of PHP experience, to help make this happen.
