using ipod touch to control relays

Only just seen this thread - but what about:

1) Commandlfusion iviewer for IPOD Touch
2) PC and/or Global Cache with IR and relay outputs

Why? - in this scenario, the Ipod Touch can control devices without a PC, and it can control the PC (think of remote interface) too.

that iviewer is perfect for the interface! thanks. the global cache on the other hand is $300... i think i'll pass on that though... but i can use some my original idea with the iviere (i think) tony g you helped me out again!

just another option. dtmf decoder chip could work too. haven't figured out the details but it would work based on tones that you would get from a touch tone phone:

most promising examples using the DTMF MT8870 ic:

another update:

looks as though ir frequencies used in remotes range between 38khz-50khz, so it should be inaudible.

i just contacted simerec to see if i could hook up the audio out wire from the ipod doc connector straight to the vss pin. they are looking into it and will get back to me in a few days.

bugbyte i probably need you to verify this works
ok... even more research and i think i've come up with another solution. this is more expensive but more versatile:

first start out with a hacked la fonera as a wireless bridge

connect it to an then ethernet realy board

then use the iphone's wifi remote control features to control the board
