"I think there might be some risk that because all recipients receive the same encrypted text (encrypted by a different key for each recipient), a recipient may be able to discover other recipients' encryption keys."

If that's possible, it means you're using horribly broken encryption. So it shouldn't be a concern if you're doing things right.

Yeah, on second thought, that would mean TLS is broken: if many people connect to a static web site and receive the same content, they would be at risk of revealing key material. However, they are not at risk of any such thing. Never mind. :-)
