Private llSay channel for land owners

This is probibly a bit much to ask, but it would be nice if there was a llSay channel dedicated to land owners, that could only be used by objects that were owned by or in the group associated with the parcel's owner.

IE:

llSay( PARCEL_PRIVATE, "Only my objects can see this" );

I say this because I was wanting to buy some land so I could have some games, but I would like to keep some functions centralized without having to worry about others evesdropping and tamering with the communication without doing key checks.

Since, as you say, this is unlikely to be implemented; you can do what I do. I use twin-key encrypted communication.

I've written RSA in LSL a few times now; It's very easy to do, although there are problems with big keys, and LSL's lack o f a biginteger type. (need to restrict keys to ~16 bit.)
