To go further with the above...I use a neat Teamspeak status and login script at my site, which I have attached. I further tweaked your plug-in to add links to the ts_active_users vbphrase and the teamspeak.gif icon. Both links point to the login script. This script might be of help to someone that wants Teamspeak access from their site, outside of VBulletin.
If anyone wants to have a look at my tweaks,
here is the link to my message forums. In my case, I use Teamspeak to provide realtime radio scanner audio feeds to listeners.
Again my thanks for a great plugin!
