But still, if someone learns your password, rather than just being able
to mess with your recordings, they may be able to exploit a bug to start
an arbitrary process on the server, right? With Mythweb, on the
otherhand the offender would need to find an apache or php exploit, and
those two systems have been patched against such exploits constantly for
many years.

This may not be important given the unlikeliness of someone with the
knowledge to do so being bothered to try, but I believe that's what
Jay was pointing out, and I'm just trying to establish whether it's
an issue, however small. I don't know, perhaps it's not an additional
weakness and such bugs can be exploited even via apache and php. Just
trying to understand.
