[vlc] QuickTime Acquisition support

[George Bray]

Neil,

VLC on Mac would become a truely awesome media swiss army knife if it
could acquire from standard QuickTime sources.  While I strongly
support your objective, I'm not skilled in the low-level programming
that this would require.

FWIW, Apple's QTKit doco and samples might show the way.

VLC's mac developers are friendly and responsive. You might catch
their attention on the dev list:

I'll be happy to provide rigorous testing, when you need it.

George
