[TUHS] NFS 40th anniversary event

[Douglas McIlroy]

"never made it outside Bell Labs" was a poor choice of words for
"never gained acceptance outside of Bell Labs".
I agree with Dan and Arnold, but I lament the fact that NFS : RFS ::
intranet : internet  RFS had the grander vision. To be fair, I must
admit that I have no idea how efficient or robust the released version
was. Certainly the original worked very well.
