I've generated documentation from the toolkit code, and posted it in the developer 
documentation pages:


Any of the AG components that are exposed via SOAP are represented by an interface wrapper 
('IW') class; for example, the venue server's SOAP interface is accessible via 
AccessGrid.VenueServer.VenueServerIW .  If you find that documentation for an IW class is 
somewhat lacking, you can look at the IW's symmetric counterpart, the interface or 'I' 
class (e.g. AccessGrid.VenueServer.VenueServerI); the 'I' classes are in some cases better 

I'd encourage people to take a look and, by all means, "write tools/add-ons and be happy". 
  We'll be adding to the developer documentation pages soon, to facilitate external
