As far as I know, it is not easy to solve this but neither is so hard. For an 
(n, t)-threshold scheme (where, I think means 'n' keys with any 't' keys 
enough to decrypt) should be like have access to this 't' keys like typing 
all the passphrases or introducing 't' smartcards. Would be a task for 

The point that I really don't know is how could be possible to allow a live 
together on keys of different nature, like finite fields one with an ecc.
