The thread title threw me off. I thought this was like a meetup thread for AoE matches. Those are always fun to have. Actually, it has been a good while since I last played AoE 1 or 2. What we need to do sometime is organize a multiplayer matchup of at least 4 players in a random map.
POST-REVIVE:
Yeesh, just watched the video, and it's like if Worms Reloaded had it's graphics and some of it's gameplay elements forced into AoE (and it didn't turn out too well).
Back to the topic of the OP, I think I found one or 2 programs that did allow for windowed play, but it screwed up some of the gameplay and even made the graphics bug out a bit (you can see the dividing marks for the graphics, especially relevant in the terrain). If anything, if we are to hold up any MP games, we would either have to resort to using the classic "Say" commands or play over Skype. I'm hoping that same program I mentioned has settled the issue with the graphics, because I'm hoping it can work like the Chaos Launcher program for Starcraft, allowing that game to be played windowed.
PR-EDIT:
I remember what the program(s) were that did the trick... sorta. It was in the AoE Heaven forum. Looking and trying them out right now.
The programs in question that have a chance of working:
DirectX Windowed Mode Launcher
3D Analyzer
D3D Windower (I think this was the one I was talking about. Please have an update)
