Thanks for the suggestions.  I'll definitely take a look at WebDAV.  Also,
thanks for mentioning the attachment storage issue.  I don't currently know
if that would be a problem for us, but it's definitely something I'm going to
look into knowing that there is a possible concern.

You can use WebDAV to access the wiki.

You can do some custom UI on top of the basic attachment feature.

But note that the current attachment storage is not that memory efficient, so
it won't work well if the attachments are big. If you have attachments less
than 10-20 megabytes, that's OK, but bigger than that requires a different
approach. This will improve in the near future (3.0 / 3.1 hopefully).

Another alternative is to implement the file exchange using another system,
maybe even plain old FTP, and only provide an UI for it in XWiki. How exactly
this can be done depends on the service you want to use and what remote
access APIs it provides.
