For those of us that use a VTT regularly, or even those that print out maps for use this would be a huge deal.
I had thought a year ago when WotC said they were going to embrace the digital medium they would provide that sort of thing, but unfortunately they haven't. On the other hand I'm much more likely to run something from Goodman if I run something pre-prepared so maps for those products would be much more valuable.
I could reproduce the maps, but that's a hobby in and of itself (I'm busy working on the ultimate game table so time is short
I can only imagine that high quality digital version of the maps already exist as a result of setting things up for printing. Sell them to us if you must, I'd be willing to pay a couple dollars extra for each product for the ability to download maps for it from RPGNow.
