If I use armory following this tutorial there is one point I'm not clear about... http://www.reddit.com/r/Bitcoin/comments/1qcrzn/protect_your_btc_investment_how_to_make_an/

If I encrypt the wallet does it mean I need the encryption pass passphrase AND the paper backup in order to do anything with the paper backup or just the paper backup?

If armory becomes no longer supported anymore - how hard is it going to be for me to restore and utilize the funds?  What kind of backups should I be making?  Is the paper backup only good enough?
