Thanks for the compliment. While I as a GlusterFS developer would like to see us get more credit for the ways in which we've innovated, this is not such a case. The basic model of forwarding operations instead of changed data was the basis for AT&T UNIX's RFS in 1986 and NFS in 1989. Even more relevantly, PVFS2 already did this in a fully distributed way before we came along. I'd like to make sure those projects' authors get due credit as well, for blazing the path that we followed.
