[OpenAFS] AFS vs Intermezzo vs CODA - how do i choose?

[hanasaki]

Hello all,

Just getting started with AFS and I have learned there are at least two 
other Filesystems that are similar (or at least I think so).  How do I 
choose between AFS/Intermezzo/CODA?

It appears that CODA is an AFS spin-off?

I will be running servers on debian sarge with kernels of 2.4.x and 2.6. 
  Clients will be the same, and at some point in the future, possibly 
Win2000/XP.

Thank you
