I think the area where we can improve DocuShare is for them to be more open on customizations. Customizing the look and feel is still quite difficult.

Another key area is license management, as DocuShare is very sensitive when it comes to licenses. A clustered virtual server almost always suffers the fate of being unlicensed after it is transferred from one host to another, as the Machine ID is changed.

Another downside is that there are only a few articles and tutorials found on the web. Here in the Southeast Asia region, Xerox is not really active in evangelizing for DocuShare.

Reports and integration with third-party applications can be improved.
Customers usually ask for a specific report that allows them to make some statistics analysis that sometimes they need but DocuShare is not intended to do that. So, it is not available at this time and they have not been able to get these kind of reports such as reports by documents added in a specific collection by a user (automatic report), reports for content being searched, downloaded, viewed etc…

Integrations with applications that uses databases are not able to do so because DocuShare does not use dynamical values in their fields of indexing.
