Thanks!  ;)  The frontend and backend use almost the same set of 
libraries so there really would be very little space or time saved. 
For example, you might think that video decode would only be on the 
frontend but the commercial flagging routines on the backend need it 
too.  Etc...

Correct, but I'd like to make building and installing Myth as much a 
one-step process as I can.  Plus, in the future, I may be able to 
make an installer dmg with everything in one to make this accessible 
to more folks.  As the MySQL client is already required, it takes 
very little extra to build the server side.  It doesn't have to be 
activated if the user already has a working MySQL server somewhere.
