Yes and no. I think Elijah's referring to the problem of encrypting a
message to a group of recipients, so that any recipient can decrypt it
up until a certain time, and nobody can decrypt it after that. We
haven't solved that problem, but we do have a different solution for
asynchronous forward-secret group communication.
No crypto innovation is involved, it's just a matter of group members
disseminating the message over forward-secret pairwise links. I think
Retroshare might do the same... but who knows? ;)
