[PlanetCCRMA] Where to start JACK?

[Charles Fox]

Hi guys, sorry this is a really basic question but I'm having trouble
finding the answer.

I want JACK to start automatically when I turn on my machine and log in.
Where is the best place to put the 
   jack -d alsa -d hw:0 
command?   I tried putting it in my .bashrc file but then it tries to
start JACK every time I open an xterm, which is not what I want.  
How do you guys do it?   I'm also not sure what would happen if different
peopel with accounts on my machine logged in remotely, I don't want their
actions to interfere with JACK on my local machine.
