Anyone here with experience in connecting Groove 3 and Access 2002/XP?

I wonder how much extra work it will take in Groove, to use Access as the storage for a meeting booking system that will update Groove meeting/calendar entries directly.

Anyone who can describe what one need to do/know about the innards of Groove , if one only has experience/competence with Access?

Regarding the competence needed, is it very specific to Groove, or more standard connectivity issues?

Would this be very different using Access/Office 2003?
Rather not have to upgrade just because of this. What would be simpler?

I am also wondering if Access/Outlook and Groove/Outlook is relevant here. Could/should Outlook be involved to ease things?

Thankful for any comments/references.
