Wow, very powerful feature!!

First question, how do you suggest that advisory messages can help with the
following? 

> I currently have many clients registering for client specific market data
> updates from a market data server. The market data server keeps a list of
> currently registered clients vs. symbols and sends the relevant updates to
> a
> topic registered by the client (there may be more than one client
> interested
> in the same market data - eg. two users in the same company). 

Do you suggest including the encoded market data registration in the name of
the topic or is it possible to include some business related information in
the advisory messages? It would be really cool if i could restart my
business service and recover business level registration information from
some state maintained in the bus!

I suppose in the simplest form, i could create a consumer of the
ActiveMQ.Advisory.NoConsumer.Topic.xxxxx for the market data update topic,
and simply deregister the subscription at a business level when receiving
messages in this consumer. Would you perhaps recommend an alternative
approach?

Thanks again!
