First, I should disclaim I don't have any first hand experience with this, although I've given it a bit of thought.
So, a couple of thoughts:
In Craig's original post, he indicated his building was an older 3 story building. I think this is unlikely to have anything too crazy in it. I'd bet the worst you have here is fairly ordinary laminated glass.
I think you should give up on the punch idea. I think you want a decent sized crow bar, hammer, Biel tool, carpenter's hatchet. All of these are going to be much more effective than a chair or bat and much more than a punch. Considering you are talking about your office, this seems like it should be doable. You could stuff a crow bar behind your desk, or do what I do - I have my earthquake duffle under my desk. One of the items in there is a decent sized crow bar. Since it is in the bag it doesn't draw attention.
Someone here posted about the danger of breaking glass and having it fall on you. The poster suggested that you want to break glass from the top with you above it. In the case of an office, this probably means being on the desk and off the the side. I think this also suggests that a longer tool like the crowbar would be better than a short tool like a hammer.
Consider having cut resistaint gloves. I think something like these
Best Nitri-Flex Coated Kevlar Gloves would be fairly optimal, but even something like these
Ansell ArmorKnit (knit Kevlar) gloves would probably be good (and they can be stuffed in a pocket) - available with "dots" or not. They are also fairly heat resistaint and might come in handy during a fire.
With normalish laminated glass I suspect you could break through it with an impact implement like a crowbar and cut it with a sturdy knife *if* you have protective handwear. Knife will probably be in bad shape afterwords, but should work.
Something like a hatchet would probably work best for cutting through the laminated glass, but I wouldn't want to break a big peice of plate glass with a hammer or hatchet that would place my hand right in the path of the glass.
I think the biggest problem is not knowing what kind of glass it is before it becomes time to find out. Laminated glass should be fairly safe to break, but you will need something to hack/cut through it. The plate glass could seriously injure you as it falls and you probably want as long of a tool as possible.
As such, I would suggest you assume it is going to fall in big, sharp, dangerous peices, but also make sure you have the tools in case it is laminated.
I think defeating the "super" glasses probably isn't a big deal because my guess is they would use them in applications where having the window open won't be of much use. Think highrise.
Another thing to keep in mind is danger to people below as you break the glass.
Oh, in regards to the punch tool for escape from an auto, I think I'd rather have a small (~12") crowbar, sturdy knife and a pair of gloves. A lot more versitile. I have such a crow bar accessible in my car. The main think you need to consider is that it doesn't become lost in the impact. So you'll need to strap it down in a serious way.
And yet one more thing. Thinking about this, I think the Biel tool may be one of the most flexible all-in-one tools for this type of thing. You can impact with it, it extends for a longer reach, and it has a hatchet like head to cut with.
In regards to the acrylic window, probably the best bet would be to pry it out of it's frame. For that, you'd probably want a full size Hooligan tool.
