AnnetteLeeb: I myself have some experience with Adobe Connect as webconferencing tool. It's not free ware, but as somebody with an email address of a german university I am privileged to get a free account on DFN :-) , which is indeed a very comfortable service offer - Deutsches Forschungsnetzwerk. As far as I understand it, it's only for german member institutions (for them it's realy very easy to use it), but may be I am wrong, and may be they know more about international (or English) networks offering similar opportunities. If it's of any interest I could ask at the main office in Berlin. Or you try it yourself, here are some of the relevant links for DFN web- and video-conferencing services:
