If the L4 people could provide us with a coherent view of the current (and upcoming) APIs and C-Bindings, that would be _great_! (hint, hint!)
The most coherent view on current APIs is available at URL:http://os.inf.tu-dresden.de/L4/bib.html.
The L4 people in charge of the new L4 API (the Karlsruhe guys) have decided to circulate the upcoming specification in a limited way first to keep discussion short and efficient. They deemed this necessary because they felt that the current draft is not self-explanatory enough to be consumed by larger audiences without overloading its developers with questions. Let's respect them regarding their decision.
No problem ;-). None of us at l4-hurd are competent enough to follow the discussions read-write. It would have been nice to provide read-only access to the discussions though [this is educational, after all!], maybe even later when you guys reach consensus and released V4.
In the meantime (and in general), I suggest using library APIs that will remain unmodified regardless of kernel version. Please have a look at the upcoming L4 environment, which exists now and is relatively well documented URL:http://os.inf.tu-dresden.de/L4/bib.html#l4env. A release is forthcoming as soon as the L4Env developers feel that their users understand and are comfortable with their libraries. Try giving them this impression! Or even better: Help them by writing a user's guide for L4Env!
Okay, let's wait for L4Env to go public. Thanks for the hint!
