It would be nice (simply to have an import/export of a character for a starting point instead of starting over for each feature update (which is why I am now simply waiting for the development to progress further, as the restarts can become tiresome especially with the slow grind with certain skills, and especially considering how smithing is being fixed (no more huge research/skill boosts from certain types of weapons....somewhat regrettably).
I am not sure how easy/practical/possible it would be to accomplish however, regarding the compatibility across update versions. I don't believe it would be, not unless it only carries over certain basic aspects such as money, skill points spent (then to be reallocated), player level.
Yes, it would be nice to have, and I'm sure something will eventually be developed once the game system/mechanics have been ironed out.
I doubt its possible, or if it is possible, it would be very complicated, to have the player's clan and clan members import/export as well (can easily seen issues of duplicate characters happening).
