What is the best way to communicate between 2 objects? in LSL Scripting Posted March 11, 2011 The only ways that I'm aware of are, as you mentioned, a remote server or llEmail(). The linked page mentions that there is a bug (jira link says that this bug will not be fixed) that makes llEmail() unreliable for inter-region messaging. So, basically, you'll either have to deal with the unreliability, or get an external server. There are many sites out there that provide free hosting with a sizable amount of bandwidth and server-side scripting support (most notably PHP), so don't write off external servers due to cost.
