So you aren't trying to stream in real-time. You're essentially trying to post an edited video with re-mixed audio online, correct?

If so, it sounds like you need your Final Cut machine and your Sync HD to receive timecode from a timecode generator, and you'll also need to feed both video sync (ie. black burst).

From there, I'm not 100% sure how you'll sync the final products. It seems to me like either you'd need to bounce a mix from Pro Tools and import that audio into final cut, or you'd need to export a quicktime from final cut and import that into Pro Tools. In either scenario, the bounced/exported file would need to have timecode embedded into it in order to sync up once you import into the other program, and I'm not sure how you'd do that.

I'm sure there's a simple answer that someone can clue us into, but I see your dilemma
