Possum (operating system, wip)

Possum is an operating system or at least the idea of one, being created mostly as an attempt to create a fun and interesting working environment.

While it mostly is still in the ideas and research stage, the basic idea is of a microkernel without users or a global file system, where security is managed inductively. "System calls" will be issued by writing to a ring buffer, and executed asyncronously. The goal is to have an environment that lends itself to small scale software where the user/developer can be perfectly lucid about their decisions.
