My original suggestion about talking to the boss was because you perceive yourself to be at the wrong end of the telescope for people to see what is going on. The key is to make this someone else's problem since you don't think you have any clout. And maybe you don't, but if someone else than you really wants this, get their help in slapping aside those restrictions. It is AMAZING what happens when that IT person suddenly finds him/herself under the glare of the spotlight for interfering with necessary company business. That approach even worked for me when I was working with the U.S. Navy, and you can just imagine how strictly THEIR security was set up. The IT staff gets the idea that they are doing you a favor by protecting you, but once someone else sees they are preventing progress, that WILL change. I've seen it too many times.
