Data partitioning is definitely a suboptimal method; there are better options.

Some options you have:

1) Forward error correction (by far the best and most efficient option)
2) Max slice size (so that losing a packet doesn't mean losing the whole frame)
3) More keyframes
4) Periodic intra refresh (not in x264 yet, but maybe coming soon)
