Multi-camera Capture Utility (Using Canon SDK)

I want to do book photography with two Canon T2i/550D cameras and be able capture both sides of a book simultanouly. Canon's official 'EOS Utility' and other softwares are available for tethered shooting and show live preview but are not fit for my requirement as they do not support multiple (read: 2) cameras. Therefore, I'd like to get a simple application developed for this purpose. Basically, all I need is **ability to live preview (both cameras) side by side as well as capturing images (again, both cameras) simultanously**. Please see this ([login to view URL]) software for inspiration. If you can just clone it with basic functionalities, that would be perfect. The app will run primarily on Windows, but would be ideal if cross-platform compatible (QT, GTK+?). Thank you. * **INDIVIDUALS ONLY.
