[9fans] Why is there no simple equivelent to plan9's pipes on linux?

[Claude Noël]

Plan 9 pipes:
- can be opened by multiple proccesses
- preserve write boundries
- will cache a single write
- 2 way
- simple to use

There's not really anything on linux that really compares to this.
Is there any reason for this? 
Only thing I can think of is plan9 using 2 files per pipe.

May be. But what about unix domain sockets?

If you're thinking of purity here, "unix domain sockets" came from BSD and are very much unlike the clean design we expect from the authors of Unix. They were formerly called "BSD sockets".
