[Standards] negative presence

I wonder if anybody has an idea about support for negative presences  
in the servers all around. I´ve tested with wildfire and ejabberd.  
Wildfire forwards messages without a resource to a negative priority  
resource (I'm reporting this as a bug), ejabberd does not. Anybody  
tested with other servers?

I'm also worried about clients. What would be the proper way for a  
client to deal with a negative presence? right now I think that he  
should not show the person as online, nor should he allow any chat  
messages to be sent directly to the resource. After all, I interpret  
negative priority as a "no chat" indication, right?

The reason I'm asking is that we are starting to test agents, small  
task-oriented applications that work over XMPP to accomplish a simple  
task. They use the same JID as my main account. Think about an  
assistant, that receives meeting requests, checks you calendar and  
accepts or denies the request based on user defined criteria. Or a  
content management system that synchronizes all his content to all  
the elements of the team via XMPP.

Thanks in advance,
