  Some questions that come to mind:
  * How easy is it to teach it new build systems (S60 and Android come
to mind here). That includes Makfile, auto-generated files, etc... If it
can... this would ease the portability work of GStreamer (and plugins) a
*LOT*.
  * What are the compile-time dependencies ? How easy/hard would it be
to use it in a cross-compile setup ? Can it run in esoteric setups ? If
we can gain new systems but lose old systems (on which auto* works
perfectly well due to only requiring a shell) it's gonna be a definite
blocker.

  CMake looks *very* tempting (he who has read the libtool code with
love throws the first stone), but we need to make sure we're not losing
anything if we switch.
