That's more of the nature of SSL certs than their inability to set them up correctly. *.example.com covers www.example.com, but not www.something.example.com. And as far as i know, you can't get a "super wildcard" cert that allows that.

If I'm wrong on the last point, please let me know, as I know a lot of people that will be very happy to find out!
