need some help

Hi, 

My name is Jonathan Kelly and I'm doing a study about security and
file systems. I've read your excellent paper "Decentralized User
Authentication in a Global File System".

Now, I'm writing a report for the university about your system and I
have a question: Do you have any new implementation, enhancement or
evaluation for the SFS architecture (especially the caching part)?
If you do so and you don't mind, please kindly provide me with this
information.

Best Regards,

Jonathan Kelly
