Hello...
I'm probably at a mid-level of Flash experience, with a good background in C++ and I've been learning some PHP recently.
Anyhow, I'm looking for the fastest way to make a tile-based map where multiple viewers can be connected at the same time. Basically it's for an online "battlegrid" for a game like Dungeons & Dragons or so that can accompany an online chatroom game...
Just a tile-based map, where small icons (even squares) can be dragged to certain positions on the map, and the map can be refreshed dynamically so that all of the users logged in can dynamically view the updates. Basically just placing pieces like a checkers or chess game, but with a couple of viewers being able to see the changes as they occur.
Any help or pointers in the right direction would be greatly appreciated!

Thanks alot,
~Jay
