How about adding an option to tunnel a mysql session directly into the PHPEd mysql settings?

As openssh seems to privde the necessary command line funtions it shouldn't be too difficult, but it saves you a lot of time if you have multiple database servers. Furhtermore, it completes the SSH support of PHPEd which is already superb for SFTP and Shell Access (both supporting Passphrases as well as Keyfiles).
