Weather maps on the cockpit PDA?

I fly with WinPilot Adv. on my PDA. It provides a color topo map that
you can turn on or off, but I mostly leave it off, as it clutters the
screen, slows down the PDA, and doesn't add much value.

Wouldn't it be great if you could load today's weather from Dr. Jack
in place of the topo map? Waypoints, final glide, etc would work as
normal, but at the push of a button, you could see where you were
relative to convergence at 3:00PM, or winds aloft, or BL Top. I
imagine the situation with SeeYou is similar.

I think the Topo maps are vector based, and I know Dr. Jack's software
provides a matrix of data points that could be converted to vector
format. Then it would be just a matter of x-fering it to the PDA
before the flight. If you wanted the real terrain map, it's not too
much trouble to switch back in flight.

Perhaps the map maker could even be web based. Anyone with the right
talents interested?
