Streaming data between nodes

[andygough1974]

Can IPFS connect 2 nodes and stream data between them.

@andygough1974 could you describe the use case more?

You can stream any data out of ipfs, for example:

hash=$(ipfs add <bigfile>)
ipfs cat $hash

will work across nodes, and stream. though, note that since the object is a merkledag, the standard unixfs datastructure has to hash the entire file before the root is known. A separate streaming datastructure, using an IPNS mutable pointer as a stream head can be used to start consuming a stream as it generates. It would look like this:

If you're interested in sending data out of band-- meaning beyond the standard ipfs objects -- you can mount your own services/protocols onto ipfs nodes. See Example: Making your own IPFS Service

We'll also have a simple pub/sub thing at some point.

(btw, worth noting that the "indexing" data structure here does not need to be a linked list at all, it can be something better, like a binomial heap, etc.)
