We do not support anything out of the box on this, but it may be possible to do via web services, they'd have to talk to the filemaker database, get what they wanted and then use web services to send that to clearspace. If this is a huge selling point i can look into this further.
I'm curious about how to import docs, pdfs etc into clearspace via the admin console. Can you detail this proces? I'm using the latest version of Clearspace.
