License for JBoss Integration Plugin 3.0?

Hi,

The license for the JBoss Integration plugin (ver 3) is about to expire. Any chance of getting a new license key?

Also, I'm curious about your plans for this plugin re licensing. Does the existence of a license mean that it will require purchasing at some point?
I ask cause I find the plugin extremely useful (many thanks btw) & I'd like to keep using it. But before I become too dependent I'd like to know if I'll have to hand over cash to satisfy the addiction. :)

thanks
Ben Sommerville
