The long and the short is I was able to "share" an iCloud calendar with my wife. When she creates or edits a calendar entry, I get an email and it shows my name, instead of hers. My iCloud account is under my itunes id, her iCloud account is under her iTunes id... not sure what or where to look, or if this is in fact current/expected functinality... Hoping someone here can point me in the right direction!
