it's real. still somewhat alpha but it's been usable and was announced
~1 year ago on ardour-dev. Paul said he'll look into merging this
endeavour around ardour-3.1 but there's no promise to that.
I've demoed it at the LAC2011 and Dave has written about it:

sure. it's not too heavy on RAM, 128MB should do; but the more the
better (video frame-cache). and you should have a >1.6GHz dual-core CPU
for decoding PAL-DVDs in real-time.
It's also possible to run 'icsd' (the video-decoding server) distributed
on a cluster.

amd64/x86-64 (GNU/Linux & OSX 10.6), i386 (Linux/win32) and PPC (OSX 10.5).
I develop and use it in on Debian. Patrick Shirkey has tested it IIRC on
Fedora/CCRMA, Dave Phillips' test system looks like Ubuntu; and Pau
Arumi has reported some bugs and success as well on Fedora.
'icsd' is pretty much disto and OS agnostic. However, Ardour3 only runs
on GNU/Linux and requires a few tewaks for OSX.
