Breadcrumb Mode

I really want a menu system that collapses all parent menu's so that you only see current level links and all of the parents to root.
To describe better, a breadcrumb, but with the sister links visible too

a menu that is normally like...

Home
Destinations
Travel & tourism
Culture
--Flamenco
----Characteristics
-------test1
-------test2
----Classes
----Dance
----The Guitar
--Art
--Bullfighting
--Customs
--Festivals
--Gastronomy
--History
Sports
Nature

When on page "test1" you only see the following...

Home
Culture
--Flamenco
----Characteristics
-------test1
-------test2

Possible? I am going to hack the module in the meantime.

Thanks
Will
