Very good writeup. I'm much the same kind of potential business user, my scenario would be very similar except for less dependency of word files, and I would need OpenVPN (I know it exists, but unless it's integrated with the networking applet it's not good enough) and java applet support. The rest would be similar (including presentation - that was a seemingly ok resolution. Although in the past it was possible to get Palm-to-projector interfaces, and it can do PowerPoint directly).
