Is there a way to have it take the RD Tabs XML format and convert that into a record in a table?
Putting a "Lockedforediting" and "lockedby" field won't pass the security muster. Anybody could go into the file share themselves and edit it by hand. The way I was thinking was to use NTFS to RD Tabs advantage. If the user is granted read-only access to the folder, they won't be allowed to edit in RD Tabs (nor by hand). Simple as that.
Additionally, my current line of thought is to have local favorites and global favorites, instead of trying to combine the two. This way you can create your own favorites, even if you are not allowed to save them to the remote store.
I might be able to bump up roaming/global favorites...
