Anyone have any real world experience they are willing to share on how AFS compares with current implementations of NFSv4?

I'm doing some research on deploying AFS vs. NFSv4 and trying to understand which might be better at this point in time. Specifically, I'm in interested in the following areas:

1)  WAN performance
2)  Global namespace (transparency of file/directory location)
3)  Caching
4)  Security
   a)  Encryption
   b)  ACLs

I found some discussions in the archives, but the ones I found were old (2003) and I wanted a current perspective.

IMHO the biggest single issue with near-term deployment is the clients. NFSv4 looks like a big improvement, but I can't find things more current than a year back about client status. At that time, the clients didn't look production-ready to me.
Darwin doesn't have NFSv4 support unless you trust an ad-hoc piece of software with no support. I remember seeing a comment about Solaris needing patches or an upgrade to 10. Linux has had support in kernel for a little while now though it may not be there by default on many distros. Of course, openafs also needs to be "enabled" on many distros as well.
