VIewer 2.7.2 has come out. After much mucking about with errors getting it to install, I finally got it up and running. We now have a much larger cache limit of 9984 MB (9.75 GB). Um… wow? Next is a new method for llRegionSayTo. It works just like llRegionSay, but can be directed to a specific target. Now your objects can send messages to each other without eves droppers or the complexity of email/web/xml-rpc. You can also talk to avatars on PUBLIC_CHANNEL zero no matter how far they walked away (within the same region). It seems to be received similar to llOwnerSay since it is that same yellow color when an avatar sees the message in their official 2.0 viewer (default settings of course).
