What is the best way to add a subpanel(?) for module related via flex relate?

I have a custom module with a Flex Relate and want to display that data on the record view of the Account, Contact, etc..

I am thinking either a custom subpanel, or an e-mail-address-like display within the module itself.

Any suggestions on an approach? Has anyone else done this?

thanks,

FrancescaS
