Microcosm Feature Suggestions

Does Event have somekind of superclass ListDriven?

I can see some value in GroupPurchase inherits from ListDriven, where each entry has more than UID, so maybe a ListItem.Options field could hold JSON representing choices.

An example might be the Mielec group buy...
Current process:

• Members express interest
  
• Interest List starts
  
• OP gets a quote for rough numbers, finds available options
  
• Purchase Intents, with option details, gathered using Google Form backed by a GoogleDocs Spreadsheet
  
• New list in thread for those who have registered their Purchase Intent
  
• OP declares payment window, tracks progress via GoogleDocs
  
  
  

New Process:

• OP creates GroupPurchase instance, provides Meta Info, LISTSTATE = SURVEY
  
• Members add themselves ITEMSTATE = INTEREST
  
• OP gets quote, options
  
• OP modifies GroupPurchase record to define options, LISTSTATE => METAORDER
  
• Notify list members
  
• Members update their entries to select options (or back out) ITEMSTATE => INTENT
  
• OP "closes" list, LISTSTATE => PREORDER
  
• Notify list members
  
• Members make payments, ITEMSTATE => CONFIRMED (or PAID)
  
• OP exports GroupPurchase info, places order LISTSTATE => ORDERING
  
• OP receives confirmation of order, delivery estimate LISTSTATE => ORDERED
  
• OP updates GroupPurchase info to add detailed delivery options (i.e. if collection requested, 1-to-1, CompassBeers, Delegate; If postage requested, Address or Delegate aka GroupedPostageReceiver)
  
• Notify list members
  
• Members make delivery choices ITEMSTATE => PENDING-COLLECTION or PENDING-DELIVERY
  etc.
  
• OP marks GroupPurchase as DELIVERY when main consignment received
  
• Tracking infos?
  
• Members (or OP?) declare receipt, LISTSTATE => COMPLETE when all items ITEMSTATE => RECEIVED
