internet question: GL meetings online AND alive

A question for the experts out there:

I want the possibility that GL meetings can be visited online. The idea would be to have a computer with camera in the meeting, so that people that want to attend, but is far away, or has to stay home babysitting... could log in and attend the meeting from home. So, I want to simply setup a videoconference system, so that members prevented to show up in the vergaderzaal could follow it (and participate in it) from elsewhere.

That would require some software. I can imagine several possibilities, but probably there are some of you people that do this already (for fun, or for your jobs). Any suggestion how to set it up?

Perhaps needles to say, this idea comes from the situation at the Kleurrijk Platform. We want to involve "multicultis" that are active locally... but it is hard to get somebody from say groningen to come regularly to meetings in Utrecht, or in A'dam. The participation drempel would be lowered if we have a videoconference system. Not to mention travelling costs... both in money and in pollution! I suppose that the idea could be useful for other landelijke werkgroepen... maybe some do it already?

I'll be looking forward to reactions...
