I'll investigate Net::Proxy. Thank you for the tip, Corion.
Sinistral: Tunneling web browsing over ssh via SOCKS is not what I'm talking about here, but thank you.
And thanks for the legal advice, but I didn't sign any contracts that dictate what I can and can not do with the Interwebs at work, nor would I ever be dumb enough to do so. It is well accepted in our environment that we're all accessing our home machines via whatever way we can, e.g. ssh or one of those sites that implements an Remote Desktop proxy as a Java applet (can't think of the URL of the site that most people use right now).
