As the other responses have indicated, I don't think there's yet a a ready-baked solution for this but rather a number 
of different approaches which each have their pros and cons (using llHTTPResponse, communicating via script with a 
backend region module via modSendCommand(), adding new OSSL functions).

I'll also add the approach of using a region module to directly create/move/delete scene objects without any LSL/OSSL 
scripting.  This has both disadvantages (can't be transferred to SL, written in C#, poor OpenSim internals/module 
documentation) but also advantages (no need to shuttle state between scripts and a backend module, no need to 
co-ordinate scripts running on multiple threads, direct access to all OpenSim functionality, easier automated testing, etc.)
