llMapDestination question

I have a line of lockets that I market to couples, that uses llRequestAgentData and proximity etc etc the usuall fanfair of stuff for this kind of item.

I was wondering if somebody could throw me a code snippit or help maybe nudge me in the right direction.

I was wondering if I could pass lets say Avatar A's location to Avatar B in a different sim via llEmail so itll show up to Avatar B as a llMapDestination (you know map pops up on screen, and hit teleport) call.

if somebody could help. Ill gladly throw a freebie line out that is a nice attachment that does only this.

If you had a central data store of some kind (server with stable key or external web server) you might get away with this (use llHTTPRequest() instead of e-mail if you go with the web server), but otherwise it would likely be better just to send a SLURL via llInstantMessage(). An attachment's key changes every time you attach it (and maybe when you login wearing it; not sure), so there will never be a stable e-mail address for either participant.

Just remember for llMapDestination to work, the prim must be attached to the avatar or it must be touched directly. It can't be used in the timer event, or email...ect
