[Resolved] soapUI plugin development question

Hello,
I have looked at the various blog post by Ole on how to develop custom plugins for soapUI. Great stuff.
I am trying to figure out if it is possible to alter the behavior of soapUI's datasource via a plugin or via some other way. I basically need to create a new datasource type and would like that to appear in the dropdown. If you can give any pointers on where to start that would be great.

Thanks

Ali
