Joe,
I have been looking for the same sort of thing for some time now. When I first signed on to the board someone was giving out a sample palm program for electricians It would do voltage drop and short circuit calcs I think, and a few other things. Will locate it and forward it if you are interested. (You may already have it)

I always thought it would be great to have the NEC available in a Palm Pilot, but figured that there would not be enough memory to handle it. Any thoughts? Maybe the NEC in an E-Book. If we get enough members from here interested maybe the NFPA would put out a beta version for all of us to use. Yes, I know I am dreaming.
