The other way, which I alluded to above, is to play over the internet with an application sharing software and cyberboard (
http://cyberboard.brainiac.com) software. If you have MSN messenger you have the application sharing software already. Cyberboard is a shareware program used to play out PBEM wargames. Phillipe Le Bas made up a full advanced ops F&E gameboard for it (good things do sometimes come from France). This means that the map is defined, the counters are defined (it's literally impossible to run out of counters), everything is defined. What you then do is click application sharing in MSN messenger, and choose to share the cyberboard program and any other relevant programs (accounting forms, die roller program, etc). When you do so both players will see the same cyberboard map at the same time. The player at the remote location can also take control of the cyberboard program with the permission of the player/person that owns the computer it is running from. What that means is that one player can make a move, and the other can counter his moves or make decisions, in real time. Effectively it's like being there, but you're not actually there, of course. Cyberboard, being a program that was originally designed for PBEM, also has a great deal of functionality to play in this manner. Frequently what will happen is all movements that do not require interaction between the players at the same time are done by E-mail, and only reaction movement and combat are done "face to face".
I have the full cyberboard gamebox for F&E alluded to above. If you want it, or want to see a demonstration of it, e-mail me and I send it/show you what I mean. I'll note that I can't get zonealarm pro to work with MSN and application sharing, and I have to shut it off to get it to work; you may need to shut down your firewall (if you have one) to make it work.
Edit: Oh, I forgot to mention, that all of this is totally free, of course.
