You cannot use DevExpress development products, such as DevExpress UI Controls, Reporting, Dashboard, or others to create a Report and Dashboard Server product that competes with the DevExpress Report and Dashboard Server. DevExpress .NET Controls and Frameworks EULA expressly prohibits this by stating the following in Section 6:
"AT NO TIME MAY LICENSEE CREATE ANY TOOL, REDISTRIBUTABLE, OR PRODUCT THAT DIRECTLY OR INDIRECTLY COMPETES WITH ANY DEVEXPRESS PRODUCT(S), INCLUDING BUT NOT LIMITED TO THE SOFTWARE DEVELOPMENT PRODUCT(S), BY UTILIZING ALL OR ANY PORTION OF THE DEVEXPRESS SOFTWARE DEVELOPMENT PRODUCT(S)."
In other words, if you do decide to create a Report and Dashboard Server it must be domain specific (not a general purpose reporting server) or not available for sale.
