Speech Recognition With Http Server?

The ability to display and control ARC (which is in a PC) using the internet and an iPad, etc, is really impressive. However, I searched and found no mention of remote speech control in that manner. Nor can I perform it on my iPad. If I have missed something please let me know.

I guess I could do it with two "walkie-talkies", one in one room and the other directed into the mike on my PC in another room. However, I can't help believing that DJ could come up with something more elegant.
