I want to run an Eberron setting game, and I'd like to use the Eberron map, which I have as a high-resolution png, but be able to add quick notes and such as the game progresses. Something similar to the way you can in Google Maps.
I have already considered using the Google Maps API, but I wanted to look for a simpler solution first.
The existing map can be seen here.
I print out my power cards as shown in character builder (9 per page), and then use a marker (candy, pennies, beads) and just place it on the sheet when it's used. For special powers (like dailies that can be used 2x per day or something) I just put multiple markers on them. Keeps things very simple. At the end of the day, I just eat... er... remove all the markers.
See my answer to What is a good combat tracker for D&D 4th Edition? for several common techniques.
We use stack-able 1" tokens (I cut them with a laser cutter), hand-cut translucent folders for non-mobile area effects, and pipe-cleaners for smaller, mobile effects like stances.
Another clever thing I've seen is all paper (download them at By Decree of the Czar)

I would recommend looking into Realm Works by Lone Wolf.
It allows you to add pins to your maps and chain content together with hyperlinked tags. You can see the pins in the map view screenshots.
