Streaming live video from wedding iPhone 3G

Next week will see me in Cancun Mexico at my nieces wedding. I was planning a relaxing wedding day of drinking but today, my brother in law, the fathers bride wants to know if I can live stream the wedding (video and audio) to his brother in Calgary and our father in law in Moose Jaw.
Im running with a 3GS 32 gb.
Just checked the app store and there doesnt seem to be an app for that. Most are for monitoring a video stream. Maybe skype conference call video????
I want to connect to a wireless internet connection on the beach, point the 3GSs video camera at the wedding and stream to the internet to a pre determined web site.
Any help would be appreciated Shannon ties the knot next Tuesday.
