I have updated the WebcamXP Component, Module and Mambot for use with Joomla! 1.0.x, which can be found here.   All three elements are installed automatically, when you install the component.

The update is just a minor one to better support the way Joomla! handles mambots, improve some presentation elements and tighten some code. 

Here's a taster of what the component/mambot can do, with a webcamxp stream via another site.
