Pardon me for jumping in the discussion, but I didn't know where else to ask this. Does Iroh support streaming, instead of moving blobs? I want to write a little p2p tool to forward one port from one machine to another. Also, forwarding UDP packets doesn't require the congestion control of QUIC. Does Iroh allow disabling it for a certain "message" or stream?

Yes. Iroh itself provides direct QUIC connections. iroh-blobs is a protocol on top of iroh that provides content-addressed data transfer of BLAKE3 hashed data.

What you describe sounds like https://www.dumbpipe.dev/ , a tool/demo built on top of iroh to provide a bidirectional pipe across devices, somewhat like netcat.

Dumbpipe also has a mode where it listens on a port using TCP.

It sounds like you want to basically build dumbpipe for UDP. You can of course use a QUIC stream, but QUIC has an extension, which we support, to send datagrams: https://docs.rs/iroh/latest/iroh/endpoint/struct.Connection....

This basically allows you to opt out of QUIC streams, but you still do get TLS encryption.

It looks like they have examples with unreliable channels: https://github.com/n0-computer/iroh/tree/main/iroh/examples

You'll prob have to check the max packet size that you want to forward because quic adds a bit of overhead.
