Looks cool, thanks. They should take the opportunity to fix a few Unix/ACL security problems though, instead of just reproducing the same old POSIX quagmire. Make chroot isolation complete with plan9-like private namespaces, don't implement the traditional broken user/group security model and instead learn from the Polaris virus safe computing prototype (they're already partway there by using the capability secure seL4 kernel).
I would personally also want to eliminate a lot of the duplication in the POSIX API, but that probably won't fly. Can have your cake and eat it too.
