Custom Presence in Red5/Sparkweb Possible?

I’m curious if there is a way to have the custom status message in Red5/Sparkweb be reported by the Presence Service plugin. It works when using a thick client, such as Pidgin, but not with Sparkweb.

Please see the attached screenshot. I would like the webpage (top of screenshot) to report “Test” from Sparkweb as opposed to “null”.

Is this possible?

Thanks
