There's not really any need to make this a feature - clients can tell from the response to the index operation if they are getting a full or brief listing. To make their life easier, we could add an attribute on the enclosing <instances/> or <images/> tag, something like <instances listing='brief'>; in the ruby client, we should support this by making objects lazy-load their attributes (IIRC, there's already some support for that) The behavior should be that we return a full listing from drives that make that cheap, i.e. allow listing with just one call into their API, and return a brief listing from all other drivers. > Also I added an option to return a full object using '&listing_mode=full'. I don't think this is very useful - for drivers that make full listings cheap, we already send them. For the others, a full listing is just asking for trouble and random behavior, based on whether we'll hit a timeout or not.
