Is there a flavor of the Remoting SDK available for Island?
If so, which targets are supported (Windows, Linux, Mac, etc.)?
Not currently, I’m afraid. no.
Is that something that you’re considering for the future?
Considering, yes, even cursorily explored, a few years back (actually more of a “native Elements & Elements SDK-based Remoting SDK implementation” that would then work on all platforms.
But just to be clear, this is not an active pursuit at this time, and even if we did (re)start it at some point in the future, it would be waaaaaays off in the distance, to be done and usable.
