Wedding livestreaming

[jack]

One of the ideas we half-jokingly suggested for the wedding was streaming it online for the benefit of the couple of people who'd like to see but really can't come. I'm not sure if this would ever have been practical, and we don't think we have time to plan it now. But in theory it can't be too difficult. Has anyone ever done something similar, and have any useful advice about how difficult it really is, or would like to have a try at setting it up themselves?
