Remote control of an ICOM rig

It would be good to operate my IC-705 over wi-fi from my iPhone. This would mean I could control the radio whilst in the lounge or even in bed! 

I am sure there are several programs, but I saw this one yesterday. It is not cheap at $36.99. There are versions for the Mac and iPad. 

One could even control the radio over the internet.
