all of the cdroms/cdplayers I've ever torn apart and powered up had red lasers. i don't think i can see infrared light... but it is a very good possibility
i don't think there is one... yet. the xmpcr had a mod that pretty much stole the digital signal from the dac and sent it out optically. its just a matter of time before someone figures it out and makes one for the direct.
because what the makers of this hardware wish to do is control the xm reciever with the pc. i assume you are talking about something like the skyfi... it has buttons and a display on it to change the chanels and the such... we don't want that. if you look at the xmdirect (the reciever used for this project) it has no display nor any buttons
one day while i was driving out of town one of my friends had a small red class IIIa laser pointer and he pointed it at a car about ten car-lengths ahead of us. The driver of the other car slammed on their brakes and pulled off the road so i could pass them. this was a pretty powerful demonstration in my opinion of what even a crappy little laser can do.
iowa state has a pretty simple system for these types of things. at the begining of the year you must register your MAC address with your university email. then every once in a while they scan the entire network for ports that are open that shouldn't be, or just large ammounts of activity on ports of worms and the such. if your MAC address is found to have a worm you are sent an email to clean it. in X number of hours they rescan your machine to see if you took care of the problem yourself. if you didn't they cut off all access besides their webpage and the university email servers. once you take care of it you shoot them an email, they recheck you, and restore your access. (great way to piss off your roommate, clone his MAC onto an infected machine)
as far as the role of the student goes i think this is an awesome system. there isn't any sort of software from them running on my machine, and its not like I'm getting scan any more than i would while i am sitting at home on my cable line. from the aspect of the admins though I'm sure this sucks. i'm not sure how much of the process is automated. i know for a fact though that the unblocking process is manual.
but hey it works pretty well
