Hi,

the best method I know of is using a suffix array (and longest common prefix array) with external memory. Here is a link to a research paper and the website. According to the paper it can handle a text size of 80 GiB using only 4 GiB of RAM. Since endless streams may contain infinite information, this algorithm cannot handle that. It only can work on a snapshot of the stream limited by memory (internal and external).

I would be surprised if that could be beaten by a different algorithm.
