Multiple updates via one RESTful call?

Is it possible to make updates to multiple variables in one RESTful API call? I'm working on a script that updates several Indigo variables with XBMC state information so triggers can be created for a movie being paused or ending, for example. I don't believe there's a way to kick the URL retrieval off in its own thread (or at least I haven't figured that out yet) and want to update multiples as fast as possible. XBMC and the Indigo box are on the same LAN but I have pretty high network volume so might have some latency and want to make the updates as fast as possible.

So can I string multiple updates in one URL? If not do you think that's a feature that could be added? I know it can be done with action groups but trying to make the script as easy for others to use as possible...

It's not currently possible. We'll add it to the feature request list.

you must have a significant amount of network traffic for it to be noticeably slower...
