Most reliable stream over mobile broadband

[simonb]

I will soon be attempting to uplink a webcast using mobile broadband from a venue that can't provide me a decent internet connection.

I tried using a RTP/UDP stream to link to the server and it sort of worked. Apparently UDP packets can arrive out-of-order which is probably a bad thing for a webcast. I can imagine this happening a lot over a mobile broadband link. However, it is also a bad thing if TCP packets need to be re-sent down a temporarily choked network and clog the whole thing up trying.

Let's say I have one instance of VLC at the venue and another instance of VLC running at another location. What would be the most reliable and resilient way of streaming video from one to the other? TCP? UDP? RTP? HTTP? MMS? ???
