Implementing DFS.

[Bjorn Augustsson]

Hi!

Some of you might remember me (August) from the MADE 2000 workshop
earlier this year. We were talking about implementing a DFS* client
by extending arla.

We're doing a kind of feasibility study on getting it done. (In 
terms of how long it will take, and how much will it cost.)

We're assuming that we have DCE working to begin with. That leaves 
us with:

* The RPC layer is obviously different.
* ACLs on files.
* No write-on-close. This means different client-server protocols, but
  we don't know to what extent and how hard this can be.
* Byte-range locking (Don't know if this is strictly neccessary, it ought
  to work without it in the beginning at least.)
* The tools. 
   * cm  (Should be farly easy.)
   * fts
   * Maybe others that we haven't thought of right now.

Comments? Did we leave anything (important) out?

What are good milestones? 

Where can we expect incompatibility problems? Most of the code in 
DFS and AFS is common, but I guess the ACL stuff might clash a bit
since they're a DCE-ism in DFS for example.

And most importantly, is anyone else interested in this? Anyone even 
willing to help out?

* Or AFS version 4 for you purists out there...
