The Pluggable File System

Note: PFS is no longer under development. It has been superseded by Parrot. These pages are for archival only.
The Pluggable File System (PFS) is a tool for attaching old applications to new storage systems. PFS presents new storage systems as file system entries. For example, here's how to make vi Grid-enabled: 
% vi /http/www.yahoo.com/index.html

PFS is an ongoing research project pursued by Douglas Thain and Miron Livny and other members of the Condor Project at the University of Wisconsin-Madison. We're eager to hear of your experiences with PFS.
