- An RPC mechanism (not built yet)
- A bi-directional multiplexing stream protocol [1] (mostly there)
- A general purpose binary encoding mechanism [2] (I've gotten bogged down with this for the past few months, but I can finally see the light at the end of the tunnel!)
The idea is to get these lower layers finished so that I can build all of my data communications related projects on top of them. One of those is a general-purpose file access system that I can build actual products on top of, such as file managers, remote filesystems, streaming services, synchronization, etc. I'm rebuilding everything underneath because the existing protocols are too chatty and bloated, not modular enough, don't work with encryption, or have weird requirements (like NFS requiring kernel integration for example, or they're restricted to the local net, etc).
