We actually have two separate secure rooms at the office with similar
requirements, the issue with this document is that it is needed on
both coasts regularly enough that transport would be a pain in the
ass. I'm working in hte other direction as well - ie. Do we really
need this? what other options do we have?

At the moment it actually resides on a windows file server, but i'm
looking for a linux based solution - either presented via samba, or
web based. Any solution is going to need to auth against AD.

I thought about rolling my own web service, but decided against it -
determining that the document had been closed seemed tricky enough
that I went looking for a prefab solution.

Standard ci, co semantics would work. None or the dms or cms systems
seem to support the 'only readable while checked out' option.

I was hoping someone would know an selinux/systemx rule for exclusive
access off the top of their head.
