What type of tools are you looking to use on the second PC? Those that already use SimConnect or tools you want to build/write yourself?
If it’s the latter, I’m in the process of developing an API (Open Source) to provide basic SimConnect access to a remote PC via its own protocol.
At present, it allows network connections to request a SimVar, which is then transmitted back to the client whenever that SimVar value changes (until the client disconnects).
The first (Alpha) release is now available in GitHub, details are posted here.
