1. Do "non-unix" apps understand the concept of a FIFO file? I know that
cygwin already has named pipe support so is there any reason to try and
make FIFO support interoperate (and what should it appear as?)

2. Do you have a reference? So far I've found lots of sys/stat.h header
files :].  If you don't are writes and reads atomic? Do all readers
recieve all the same data from each writer - or do they pair off? (That
sounds rather dirty I know :])
