I have used TouchOsc with the old LiveControl template on Windows 7, it worked well enough if that's what you want (a version of Live on your iPad)
I can't say much more about setting that up unless I know what platform you are on. Really the crux is setting the output IP address and ports on your TouchOSC.
In the end I found it a little limited and not entirely what I needed.
Cut to the chase: my opinion
If you want a dedicated Ableton Live interface with 1-to-1 correlation on your iPad you might want something like TouchAble, because the old (TouchOSC based) LiveControl is a bit dated now. It can be made to work, but it's not the best a man can get if you want a specific AL interface
If you want a custom interface with Ableton Live, like - you want to grab a few track volumes, or the transport or BPM - then I'd say get something like EraserMice's OSCulator pack. That's all I needed, because I am using TouchOSC to control Reaktor, and I just needed a few bit of additional info from Live.
