How do I create a visual "window" into Ableton's GUI within a m4l patch

Specifically what I'm trying to do is superimpose a transparent slider over a graphic display of an audio waveform from Ableton's clip view, so I can select clip start points in a visual way, and furthermore have this display/invisible slider on my ipad so I can do it with my finger, with the other hand triggering playback from my midi keyboard. I have browsed available ipad apps such as Touch OSC, TouchAble, Mira, etc. but none of them seem to provide a visual window into the Live application. The closest thing I've heard of is Touch Innovations' Emulator 2, whose "portal holes" allow for such windows, but this software is unavailable for i0S.
If I have to, I'll use Emulator 2 for the "portal holes" and then just use a screen mirroring/remote desktop app from my ipad such as Splashtop, Duet, or Reflector. This seems clunky and I'm worried about latency, seeing as this would give me a chain of 4 applications (Live, M4L, Emulator, and say Reflector).
I'd rather cut the middle man and find a way to visually represent the graphic waveform from Live's clip view, perhaps with some Ableton ipad controler app that I haven't heard of, perhaps inside the max patch itself. Maybe there is a solution with Jitter? Maybe there is a way to fool waveform~ to display Ableton's clips?
Thank you for your thoughts!
