you can give doncam a try by using the vlc media player. There is a version of vlc for windows, os x, and linux.
from the linux command line $ vlc http://188.8.131.52:8080
for GUI users, put that URL into vlc however you normally do it :)
note this is experimental, round 1 version of doncam. 320x240 motion jpeg video with no audio.
