In  camera_firewire_live.rb you are trying to connect to a corba name 
server on a computer called asgurad.local (just uncomment the line if 
you want to use the one from the local host).
In both scripts you do not start the cameras and I guess you do not 
start the cameras from another script therefore TaskContext.get is failing.

see http://www.rock-robotics.org/stable/documentation/runtime/index.html 
for a documentation about how to start components.
