Hi,

I'd like to create paper backup of my private keys.
For some clients I managed to open About -> Debug -> Console and use dumpprivkey

How can I do it for these coins: PPCoin, Novacoin, Devcoin, i0coin?

And how can I restore them later?

(maybe Novacoin has debug console, but on this "cold" Ubuntu machine there is no menu visible in the top panel )
