An iPhone app as a remote control for an iPad app. Is it possible?

[Ken Corey]

Well sending a command and getting a response is a simple enough 
protocol once you're connected...but how do your devices find each other?

I'd be shocked if you could do network broadcasting using rreSocket on 
an iOS device (you might actually get away with it on a desktop, but 
I've not tried it).  Note that with the several extremely low-cost (as 
low as <$50) linux devices out or coming out soon perhaps an iPhone is a 
little over-priced as a remote control?

Anyway, one way might be to let your users do the work:

You would use the function "hostNameToAddress(the address)" to find out 
the address of the machine upon which the program is running, and then 
show that to the user, asking them to enter it into the other device as 
the target.  (note that this happens on both devices).  Bonus points for 
saving the address so the user doesn't have to type it again.

At that point you can call the functions in rreSocket to open/write/read 
to and from the socket.

Define your protocol before you start coding though, or you'll be wading 
into a marsh.

FWIW,
