Support for multiple virtual display for multiple clients

[wildhevire]

Hi, I have 2 client and 1 host setup mainly for external display use.
It would be nice if we can associate single client to single instance of virtual display. So, if 2 client is connected, 2 virtual display is created by Apollo, similar how spacedesk works.

Currently I have Apollo and Sunshine+parsec-vdd run at same time as workaround for this problem, so far works nicely but it would be nice if Apollo able to handle it all

EDITED: Sorry i dont read your wiki enough, apparently you have guide to run multiple Apollo instance. But still, it would be nice if single Apollo instance able to manage it like Sunshine do channel, and associate each channel to single virtual display instance

It was a goal for me to implement multi session support, but the code is a total mess that makes the goal very hard to achieve.

It's still on my list though, but is not likely to be done in the near future.

Channel wasn't ment for multi sessions, it's just a limit to how many clients can share the current session. It's already removed from upstream and I've merged that commit here, as Apollo has permission system that can handle multi client scenarios better.
