I have, for the first time, hosted a Skype game. The troops are my Pendraken ~Seven-Years-War armies, the scenario is "Wagon Train" from CS Grant's Scenarios for Wargames. The rules are Ross's Hearts of Tin, the latest edition of which can be downloaded from his blog.
In a Skype game the host end up manipulating all the troops on the table, his and his guest's, while the guest must try to figure out what the troops are from the images he can see. For the guest's eye view see Ross's post on the game.
Heath Robinson, but it got the job done.
