Folks, just from a design point of view: The more custom shortcut's are
being added now, the more burdensome it will become later to add more
versatility to the overall infrastructure for keeping either more viz
machines or more and different feeds (see below) in sync.
Obviously this is not my own finding, it's general knowledge and has
been proven in many, many design excercises.

As mentioned above, feeding aircraft, ships, railways and whatever else
from various sources will render the system unmaintainable (at least in
the long run) if clear abstraction layers are not being considered and
it also won't facilitate the task of interfacing FlightGear to other
sim networks in the future.
I've been mentioning HLA because it's the tool precisely made for this
sort of interfacing complex simulation setups together. It provides
nifty features like, just one prominent example, time-stamping (or time
management in general): Pre-calculate the route of an aircraft carrier,
feed it to multiple sims in advance and the ship will show up on every
of the participating machines exactly at the desired position exactly
in the desired moment.
This is not a feature to be hacked into FG as an add-on, no, HLA is
bringing this to you at no additional cost. Think of the same for AI
aircraft or cloud positions.
I think it's worth to keep this in mind,
Martin.
