netmeeting

for the installation we also checked out the netmeeting software with a webcam. the advantage was, that the chat channel was allready there and we could have a two way communication. 
but there were also some arguments contra:
the picture was very small and bad quality.
the interface separated clearly the text from the picture.
there was no possibility to save the text.

the netmeeting solution was a very hot candidate during whole friday. but in the evening we made some tests with the two projectors and the solution was more convincing.
