Idle Thought of the day: given that mIRC and Opera don't really go prod in the registry when installed... if I burned them both to a CD from my computer at home, then carried the CD with me, would they run on any other (Windows) computer? Because if so, I wouldn't be limited to a single computer at uni anymore, and I wouldn't have to install anything... hmm. Worth a try I think.

mirc should work fine, I'm not sure about opera though
