Sounds like you want access to partial binary data. There's some propitiatory features in Firefox which lets you do this (added ages ago). See [1]. However for a cross-platform solution we're still waiting for streams to be available.
Hopefully that should be soon, but of course cross-browser support across all major browsers will take a while. Even longer if you want to be compatible with old browsers still in common use.
