Genuine internet loss is rare.
Real life getting in the way is common. If the doorbell rings (or the phone, or a child cries or, or, or the list is endless), I do not want to turn around and find the character I have been building for months has had his ship blown to smithereens by some pirate who was not even on the scanner, and I loose a pile of value in fees of various types. Elite by its very nature is a game where checkpoint cannot sensibly happen all the time: if you only checkpoint when you dock, you may have 30 minutes or an hour to worry about. How many of us will ever feel comfortable that we will be able to sit there for 30 minutes without an interruption of any type?
But we need to make sure that any system designed to minimise problems when real life gets in the way. So, in particular, we cannot llow a pretend doorbell ring to stop you being frazzled by the bunch of pirates bearing down on you. I believe we need some sort of system where you can effectively do a pause (how we articulate this in game terms - a jump into hyperspace, a cloaking device, or whatever, hardly matters now), but where you must spend some time setting the pause up. So a period of time when the ship is under some sort of unsophisticated AI control, where those pirates bearing down on you have plenty of time to finish you off, but if you go into pause with a clear scanner, you expect to get there. Then, at least, we should be able to support most, but not all, real life interruptions.
