Searched and didn't find, so I'm posting, partly for my benefit and also in case this idea helps someone else.
I've been mulling some ideas for a plugin in my head. The player would start as the citizen of a certain govt. One of the choices the player would have during the story would be abandoning the initial govt and joining another, which might potentially anger the initial govt. If the char's initial system was part of that initial govt, this would pose a problem if the player later ejects (or is ejected) from their ship (which is why the Bible wisely suggests making the initial system neutral).
What I'm thinking, though, is this: what if each govt had its own escape pod outf, purchaseable only to its own citizens. The starting ship would set a magic bit in the Contribute field and not be purchaseable or capturable. Each escape pod outf would set a different bit when purchased (and clear all other escape pod bits), and would be impossible to buy while the player is in a starting ship. Finally, there would be a cron of duration 0 for each govt, with that govt's escape pod bit in the EnableOn field, and the starting ship magic bit in the Require field. The OnStart field would contain Mxxx, moving the player to the designated start system for that govt, and the OnEnd field would clear the escape pod bit.
The end result should be that if the player PO'ed their starting govt and later had to eject, they would get (instantly, to the player) whisked away to their new govt's designated starting system. I have to admit I haven't tested this idea yet. Anyone see any flaws? Can it be done more simply?
