Is this the first ever practically-deployed use of a threshold scheme?

Apparently the DNS root key is protected by what sounds like a five-of-seven
threshold scheme, but the description is a bit unclear. Does anyone know
more?
(Oh, and for people who want to quibble over "practically-deployed", I'm not
aware of any real usage of threshold schemes for anything, at best you have
combine-two-key-components (usually via XOR), but no serious use of real n-
of-m that I've heard of. Mind you, one single use doesn't necessarily count
as "practically deployed" either).
Peter (who has two more Perry-DoS-ing conversation-starter posts to make, but
will leave them for awhile now :-).
