VASSAL is an excellent tool for remote play
This evening I played remotely using vassal, the arkahm horror wiki, and google video. I can state that the tracking mechanics of VASSAL (with all expansions installed) offers just the right amount of support to provide for remote play over webcam.
The webcam, positioned a laptop's height above the board facing so that the text is readable on the webcam, provides an excellent view of the board and associated tokens. Monster tokens should be inserted into plastic holders and be upright instead of flat, for more effective visibility.
A character should be maintained within VASSAL, with item cards being taken from decks in the real board with a quick "choose from deck" within vassal. It is fast and can be done while other players are taking their turns. While it is necessary for monster details to be read out, playing via webcam and vassal is far better than not playing at all and something that I will do again. In fact, it is better than actual play within VASSAL, due to the feeling of actually sitting at the board and the ease at which players at the tables handle cards and deal with the physical interactions required of the board.
