I wonder whether matchmaking is still relevant for TUS... I need matchmaking for the game I develop and it's a concept I'd like to delve into anyway in spite of TUS inactivity, so maybe I could come up with some solution as a by-product of my experiments.
For instance,
Steam has a detailed description of how their matchmaking services work.
yes, also wa:// links, the website would host a game for you and offer you to click on your WA link to open WA.EXE to host the game with the needed parameters (not compatible with WormNAT2 !)
I also thought about that, so basically there could be a proxy lobby similar to WormNET one (with chat), but also with an ability for automatic pairing, notifications, beeping,
alarms. This would be a small desktop app built upon a tiny game engine that would connect to a matchmaking server though, hmm.
Just my 2 cents, don't expect anything.
