I do not see the benefit of cross server switching at all. All it does is dilute player numbers in the main server as there is little anyone would use the main server for EXCEPT PvP.
Its not cross server switching, its simply allowing players to adjust the amount of PC interaction to a scale they feel comfortable with, otherwise you really risk people quitting, or at the time not backing at all.
How many PC's do you actually interact with and get to know in an MMO anyway? What makes you initiate such contact?
If this is the direction the game is headed then I wouldn't be too happy; and it seems that half the the people here agree (at the moment anyway).
The game was and is well laid out many months ago during Kickstarter:
"In the game, you will of course begin with a spacecraft and a small sum of Credits. You will be able to trade, pirate, bounty-hunt, explore, and salvage your way to wealth and fame, building on those key elements of the previous games, and with sumptuous graphics only now possible with the performance of today’s machines. Only this time some of the ships out there will be other players like yourself – other members of a secret ‘Elite’ group of space-farers…
· Multiplayer: you will be able to control who else you might encounter in your game – perhaps limit it to just your friends? Cooperate on adventures or chase your friends down to get that booty. The game will work in a seamless, lobby-less way, with the ability to rendezvous with friends as you choose. This technology is already working, using a combination of peer-to-peer (to reduce lag) and server connections.
· Play it your way: Your reputation is affected by your personal choices. Play the game your way: dangerous pirate, famous explorer or notorious assassin - the choice is yours to make. Take on missions and affect the world around you, alone or with your friends."

Yes, diluting the playerbase was always on topic when these discussions took place and ideas were floated argued for and against many ideas at the time.
If someone chooses an offline player the character should remain that way, single player online is simply really someone whose grouping precludes other PC's joining the instance, now we're getting close to actually testing it we shall see how it works in practice.
