I'm investigating whether or not it is feasible to add support for ASCOM Alpaca devices in INDI. Alpaca devices do not require Windows to run, and operate completely on a REST API, with automatic discovery via UDP broadcast.
I've successfully tested a CoverCalibrator with automatic discovery, and I'd like to see if the community sees this as a useful tool.
I believe there may already be some work on going in this area by someone called “Mark” over at the alpaca developers forum. You might want to touch base with him.
