Accessing presence information from the current C2S process

I'm writing an implementation very close to Google Talk's shared status extension (http://code.google.com/apis/talk/jep_extensions/shared_status.html). So far I've managed to implement most of the features except sending out presence information to all subscribers. It currently loops through all of the resources (ejabberd_sm:get_user_resources()) and grabs the presence information via ejabberd_c2s:get_presence() but get_presence timesout when trying to grab the presence of the resource that this hook is running for (the hook is being ran on the same process as get_presence is trying to get information from).

So my question is: what is the best method to implement this kind of functionality? The only reason I need to get the users presence is to access the "show" value since the whole point of this extension is to change the status I already have the status I want to send out. I can't just get show from one of the resources and use it for all since each resource can have its own show value.

tldr: How can you get the current presence of a user when that user is the one requesting the information since you can't use get_presence() since they're the same process.

Thanks
