You don't need a service, though perhaps you need a syntax.
If you have a statement saying
	"There is at least one holder of both K1 and K2 on <date>"
signed by both K1 and K2, it carries as much information as a service 
could actually verify, e.g. either one person walked up to the counter
and demonstrated the ability to sign with both keys, or the service sent
email to the addresses used by the two keyholders and received
signed responses.  Is there some other meaning that you can't get by
do-it-yourself signing?  The interesting cases are when more than
one person or email address has one of the keys....
