Well, I'd presume that for the non-dedicated shipyards, a single yard is sufficient.

You don't need uberfast production everywhere, and your really don't want to spend the time building an ubershipyard everywhere at the expense of ships.

Something you may be interested in is what I did for P&N.
As you may or may not know, P&N has QNP, so bigger ships need proportionally more engines to go the same speed as smaller, lighter ships.
Clearly the AI files have to change.
What I did was write an AI Patcher program, which quickly zaps the files into shape (just click on the file you want to patch).

This works for normal AIs and TDM AIs too, and is quite simple to use (AFAIK).
I've enjoyed many a game of P&N vs the likes of the Vaxin and Klingons.

If the change to the files is as trivial as what I posted below, I can add support for your mod to my AI Patcher in a matter of minutes, if not seconds.

Think about it, and let me know. (You can D/L the AIPatcher from the P&N downloads page, in my sig)
