> My view of what ideal 'LVQ' behaviour would be like is that the 'queue'
> would really be more like a 'topic' where the last message for each key was
> always saved. Clients would subscribe to it and receive the last message
> published for each key and subsequently any updates (i.e. any new messages). I.e. the consumers are always non-competing.
> Rob Godfrey also points out that if subscribers fall behind they need only be sent the latest for every key (i.e. any superceded values can be skipped).
