It appears that NW6.5 is being phased out. I think that this is a
mistake, as I find NW 6.5 to be more stable and hassle free then the
other options.

The one big question I have is SALVAGE. I like the ability to go back
to dozens of versions of a spreadsheet or word document when a user
screws things up.

Does OES have the same feature? Does it work the same way?
