I have several questions:
1)What does "simplified versions of IPC control" refer to?

2)"all kernel resource allocation is under control of a user-level policy
server" - does the user-level policy server refer to Iguana?

3)Can these features you noted be found in current Pistachio-e and Iguana
release? All they belong to close-source part of OKL4?

Thanks!
