Using Percussion CMS with a Digital Asset Management system?

We’re scoping out Digital Asset Management (DAM) systems to store all our artwork, videos, etc. Has anyone got any experience of integrating such a system with Rhythmyx? We’d like to keep the high res versions of artwork in the DAM and connect that to the web resolution versions in the CMS.

Contenders for the DAM range from Canto Cumulus to ResourceSpace, but we’re open to suggestions of other systems, especially if they’ve been successfully integrated with Rhythmyx.

Thanks in advance,
Steve
