So you need break, parity ... no be serious please

So you need a tiny kernel side driver to unpack it into a meaningful fs, or just a user-user channel with a daemon each end and a protocol over it - nothing kernel in that.
We don't implement tcp/ip http sessions as tty devices with the kernel as web server and the same logic applies here.
