I have a cheap and cheerful webcam - the dreadfully named "TwinkleCam" from Chicony.
It works under Yoper, using a driver from the web - the sonixcam driver. I believe it is also the same driver ( and camera) as one of the Trust models. Quality is OK - basic CMOS webcam. There is a driver in the kernel which is supposed to work - the sn9c102 driver - but it is not for this particular model.
As for Gnomemeeting - I understand this does not work yet with Yoper
I have had a fiddle, but so far, no joy. It was being worked on before the Yoper forum went down - so hopefully it will be sorted soon. Typically, you will get an error about libebook.
I have been running my webcam under Gnomemeeting with other distros - Mandrake 10 for instance. For now, I use it simply for outputting regular shots to a web page with Camstream - which is a neat little app, but it won't do communication.
