I presume that it would fail, actually I'm sure of it.
When I'm streaming video late it night, when my IP address changes at midnight my stream stops, I have to click play again. I'm presuming that in your case switching from WiFi to 3G/4G etc would have the exact same effect. Not only does will the IP address and MAC address change (be different), but the whole route that the data on your device takes (hops) to get to its point of destination will also change.
So as far as I'm concerned it will fail without a doubt...
