NodeA_NameSpaceA, NodeB_NamespaceB -> both shared to NameSpaceC.

Shouldn't the two of them be able to talk? This includes routed subnets.

This doesn't appear to work that way. I would have to either have to share NodeA in NameSpaceB or vise versa.

Otherwise this is pretty awesome, thanks.

Shared nodes do not expose their subnets, to match the behaviour Tailscale.com has (https://tailscale.com/kb/1084/sharing/#sharing--subnets-subnet-routers)

And shared nodes to a namespace do not see each other, also to match Tailscale.com behaviour:

Company A has two shared nodes from Company B and Company C. It would not be very nice if B and C are able to see each other :)

I am afraid this is one of this Working As Intended™ cases.
