Another possible application for iPhone/iPodTouch/iPad, is VNC.

I haven't had time to investigate VNC and really do not have the need for it, but it apparently can turn an iPodTouch or iPad into a big wireless remote.

Here are some comments (from another forum) from a fellow explaining it for remote-computer-control of astronomy software, but it ought to in principle work the same way for Music. Imagine having the PC running Band-in-a-Box, controlled from an iPad on the music stand, wirelessly mirroring the chord sheet or notation view. Maybe it wouldn't work out, but then again, dunno why not--

The fellow's comments--
"I've used an iPod touch to remotely operate TheSky, but the small screen was tough for me to see without a lot of magnification. My setup is RealVNC running on the observatory PC and the Mocha VNC client on the iPod. Mocha displays the screen on the remote PC and has an on screen mouse pointer with left/right buttons for selections and it uses the iPod's virtual keyboard for text inputs. "

"The new iPad has a huge display compared to the touch, and it looks like an ideal walk-around remote control with no moving parts or dangling cables."

"James C Chandler Jr said:
It is neat that someone wrote an iPod app to do something so specialized."


"Actually there are at least five VNC apps for the iPhone now, and they all do a decent job of showing the display on the remote PC. Most VNC users are people who manage IT sites with dozens or even hundreds of servers. With an iPhone VNC app they can pop on the network from almost anywhere to check server logs and keep tabs on any that are off-line."

"I like Mocha VNC because it has a virtual two-button mouse and TheSky6 needs it. All iPhone apps will run on the iPad now, but a developers kit released Tuesday allows creation of apps specifically for its larger display and additional features."
