I wouldn't be the guy to work on the code, not being a game developer or even adjacent to it. I work in ISP/telecom core network infrastructure, so would be happy to help out with questions on stuff like DIYing a set of self-hosted servers for a revival of the game.
Yes I'm aware it exists, was thinking more of what theoretical infrastructure might be needed if the full art assets/code/etc for the final release of Forged Alliance was open sourced and further built upon. My understanding is that FA Forever is a group of people who've implemented a server replacement since the officially-hosted multiplayer servers went offline some time in 2012.
