Sorry, I asked Chris about these but then got distracted and didn't get back to y'all:
AI Enhancement - AI Command Carrier:
Ok; not for the short-short term, but we'd like to do it.
Destination ETA:
Cool, we'd like to do that too, once things calm down a bit.
Rally Post Forwarding:
Ok, it's going on the to-do list for later on.
On the others:
I am not particularly in favor of the transport change, as I feel like that encourages deep turtling, whereas instead the current model encourages beachheads. Also the jump drives thing are incredibly far out of scope, that's something for an expansion or not at all.
And the retaliatory guard post is pretty out of scope for the time-being; we actually have some other plans for the micro-expansion which might make that redundant anyway.
