A few thoughts I have had recently include:

The combat menu should have a transporter option--allowing you to escape being IG'ed at the (possible) cost of your ship.

A game setting for returning from being ship destroyed that will attempt to place you in one of your navigation point settings and then Terra as a last resort--the requirement being you have one or more personal or corporate fighters placed in the sector.

I am not certain if this is an oversight (at least in v2), but it is virtually impossible to invade a sector that has a very large number of fighters down but no planets or manned ships at the time of entering the sector, and while the adversary is running a script to pwarp/twarp and being equipped with an PIG/IG, the only outcome is to become ship destroyed on the first attempt. (But the reaction seems to work differently if there is already a planet or manned ship w/ IG in the sector prior to entry.)
