Those bounds (or perhaps the near lack of them:) will require some optimisations to be applied in order to achieve reasonable runtimes--depending upon what you designate as reasonable?

One difficulty with looking at a problem that is as open spec'd as this is knowing where to concetrate your efforts. Do you have any "typical" samples of the datastreams that you could make accessible? It's an interesting problem that I'd enjoy pursuing a bit further.
