Named Pipes may be old school, but while MapRFS will support them via the NFS API, it would be nice to have them as part of the MapRFS and part of Hadoop.
I guess the lack of interest in this is that not many shops are programming at that level. It would also be novel in terms of no other HDFS provider would have it although they too could provide it... to a point. It would mean a bit of work on the FS and not a simple extension due to the chunking of the files and the data locality of the files.
Thanks for sharing your idea. Don't forget to promote it and vote it up.
