How to Display "Tabbed" content from Views in Panel / Pane in Node Template
In the end, I used the "Panel Tabs" module. It is available in dev version, which gave me pause, but it works well on the main platforms (Chrome / iE / Firefox); I haven't played around on Safari. 

With a little css, this will be a good working solution, but I would be interested to know if others have a more standard approach.

Thanks,
keb
