I think you could make it an NT Service. See a howto to take any app 
and make it an NT service. ?Doesn't say making it headless prevent a 
window/UI from appearing?

Mmmm Can't say anyone has build a headless macintosh VM for quite a while.

There is a IHAVENOHEAD #ifDef that was placed there a few years back, 
you'd need to compile with that defined. Also for OS-9 you could 
change the application flags to say it's a background process, which 
will prevent it showing in the list of applications. Originally it 
would start with no window, but still appear in the finder's list of 
applications so you could kill it.

For OS-X nothing really to prevent you from building it as a app with 
no user interface, then spinning it off in a terminal session. But 
I've not done that, however tools to build your own are free.
