Please explain the relevance for the uninitiated.

The Zw stuff looks like Device Drive APIs, where as we want 
Userspace/Application APIs.

There is no documented type for 
FILE_INFORMATION_CLASS=FilePipeLocalInformation in the Zw functions.

So my stance is still the same.  A MS rocket scientist is still 
necessary requirement to continue with the existing approach.  The 
rocket scientist will understand things that mere mortals wont :).


Maybe you are in a better position to share more insight into the 
situation (specifically about the use of NtQueryInformationFile in 
addressing the writability semantics of the POSIX select/poll/write 
event system).
