More than 2 Tabs

Does anyone know how I can do multiple tabs on my info windows? I have
read Mike's tutorial over at
http://www.econym.demon.co.uk/googlemaps/tabs.htm , so I need to be
directed somewhere other than that.

Any suggestions on how I can add different numbers of tabs (up to 8) to
different infowindows?

Of course, if this is impossible with the current API, let me know that
and I'll do something different.
