Yes, this is not a matter of people who are too lazy to attend but instead people who cannot make a wedding because of some reason. Those reasons could be elderly family members to those in another country or location.
I think in this modern world being able to live stream a wedding is fabulous. There is no doubt some people would object to this but of course those people hate to see improvements.
Having the facility to live stream only adds to the fabulous world we live in. Like Skype for distant families and Facebook for keeping in touch.
Yes, live streaming weddings is a fabulous idea – go for it.
