I've been asked to help set up a way for a volunteer animal rescue organization to use an application to keep track of animals they've rescued. This application already exists, and can use it's own local database or connect to a MySQL database server. Since there are several volunteers spread out over a large region, a database server would be the best way to go. Money is a big problem, obviously. So, I'm looking for a very cheap or hopefully free database server or webhost that allows tcp/ip connections to their database servers. Backups will be handled on our end, so basically I just need the hosted mysql server.

I've seen 000webhost.com, x10hosting, and xtreemhost, which all look promising, but they either aren't clear on remote mysql connections, or don't allow it at all.

Looking forward to your recommendations! The animals thank you! :)
