[kepler-users] best demo workflows?

[Tristan King]

Hi guys,
I'm just wondering what workflows you guys generally demo to people  
(especially scientists) who may be interested in or who you're trying  
to get interested in using kepler?
I want to get some good workflows that i can get working under my web  
portal to demo to potential users, but i find that most of the  
workflows (at least all the interesting sounding ones) on the cvs  
server are broken.
If anyone's got some golden workflows that run with the trunk of the  
cvs i'd be very thankful if i could get my hands on them :)

Thanks
-Tristan
