I find this somewhat puzzlling, since according to my sources DCE
development (source and builds) has been in DFS for quite some time now.
But I will let someone from OSF give a better assessment oif this
situatiuon.

There is an AFS/DFS translator product from Transarc which allows a smooth
transition. I have asked folks from Transarc to expand on this.
As for deployment, there is a small development site (of roughly 10,000
clients...) in Austin that belongs to even a smaller company (IBM...) that
is moving their entire operation to run over DFS. NASA Langley has 2000+
researchers whose entire daily activity (home dirs, files, programs) is
conducted in DFS (off of 4 servers I might add). There is definitely a
growing trend of customers that are considering the use, and have plans to
do so, of DFS. Are there more DFS customers today than there are AFS? No.
Will there be? I believe so.
