As most of the server side of Second Life is still closed source, only
Linden Lab could implement such an sim-to-LSL interface.
http://jira.secondlife.com/browse/SVC-58 seems to be what you request,
so you might want to vote for it.

If the data should actually be displayed to the end user and a script is
just used to fetch it (e.g. for display on a HUD), that could very well
be replaced by new functionality of the viewer, which is aware of other
avatars on the same sim even outside of draw distance (the data is
needed for the mini-map anyway). To see what's possible there, have a
look at Dale Glass' modifications to the viewer:

Of course, if the data for some reason has to be processed in a sim-side
script and LL doesn't implement SVC-58, you could still get a modified
viewer (or a bot) to transfer it back inworld via hidden chat channels.
http://wiki.secondlife.com/wiki/Alternate_viewers#Marine_Edition uses
this technique.
