Please look at:
which shows pictures of our fully featured Mac AG node being
demonstrated at the APAC05 conference (Sept., 2005, Gold Coast,
Australia). "fully featured" means 4 capture streams and 4 display
outputs (at the conference we used 4xLCD's rather than projectors).
So, it is definitely possible. However the performance is somewhat
sluggish compared with our all-Linux nodes and hasn't been installed
in a "proper" room for ongoing use.
Credits: the development work was carried out with the support of an
AUDF (Apple University Development Fund) grant. Most of the software
level work (recognising multiple video inputs etc) was done here by
Doug Kosovich and has been incorporated into the current AG
development tree i.e. it will be part of AG3
