Does the server have to run headless, or can one person still run games locally on it while another has a remote session? That is, would I be able to play on the monitor/mouse/keyboard directly attached, while my partner has a session on a laptop?

Very cool!

When you specify To: localtesting@aussie.zone how does the bridge know if you meant https://aussie.zone/c/localtesting or https://aussie.zone/u/localtesting instead?

I’m no lawyer so I could be completely off-base, but I think the existence of homebrew can make all 3 points defensible, depending on what evidence exists about their primary intent being breaking the DRM. If they have posted publicly things like “this patch should bypass DRM for this particular game” then they would be screwed, but posts like “supports/extends this feature so we can better emulate the functionality in this particular game” should be fine? At least if I understand the precedent set by the Connectix ruling in addition to the wording of what you pasted?

Maybe everyone else is seeing something I am not, but what routing path is for internet traffic to "Future PC" and its neighbors? You have the ISP modem labeled as a passthru, which means it is not handling NAT/firewall. What device is binding to the WAN IP address that the passthru will be handing out? An unmanaged switch is not going to do that.
