One of the short comings of Adobe Bridge is that it was designed as a unify package. Reading between the lines Adobe does not intend to adapt it to a multi user server enviornment. How well does iMatch work under these conditions - multiple users accessing several servers and adding or moving imagery around?
I recommend the topic Sharing Databases in the IMatch help which explains how to share IMatch databases between multiple users.
If you don't have IMatch installed yet, you can download he help separately from https://www.photools.com/download.
If you want to make available IMatch as a server-based DAM in your network, you might find that the upcoming IMatch AnywhereTM product may be ideal for your requirements:

IMatch Anywhere is almost finished and will be released soon.
