Why not just have a file that a client reads that lets the client know of changes to files.
client opens this server-provided file ("changes"? "dnotify"?) Server agrees to send client info about all FIDS which client has active that are changing. Form of the message? fid[4]offset[8]len[4] It's up to the client to figure out what to do. if the client doesn't care, no extra server overhead. no new T*, no callbacks (which i can tell you are horrible when you get to bigger machines -- having an 'ls' take 30 minutes is no fun). No leases. The fact is we have loose consistency now, we just don't call it that. Anytime you are running a file from a server, you have loose consistency. It works ok in most cases. ron
