Hi Jack,

I got the node to run under macosx as well. When compiling I had an 
error with two uint declarations in camera1394.h which I fixed by 
substituting with unsigned int. I had problems with the default mode 
settings, so without changing these (or setting them as inital 
parameters) the process got locked up. I guess this is a camera specific 
problem. Also there is one notorious problem with libdc1394 on mac and 
that is a warning message that occurs for every sampled frame saying 
"libdc1394 warning: packet .. had error status 0". That can be fixed by 
commenting the respective line and recompile library however, so that is 
also no shortcoming of the node. Anyway, will continue trying..

Cheers,
Klaus
