Just checked it out.
IF your mini has the server setup, running and you have have wifi between the 2, then I7d say, yep you can.
I just don't know how many system components you can access though ...
I just found this App and I didnt know if anyone else might think that it can be used with a mac mini in your cars.
It allows for almost full computer control through a webserver on the computer.
Cant code cause I dont know how, but give me the paint bucket and my eraser and have at you!
