Exactly right. DayTrader was not designed as a showcase scenario. It's  
a performance measurement device. I would not consider it a template  
for good SCA design practices.

One DayTrader plus would be the breadth of technologies that it  
incorporates (servlet/JMS/EJBs). However, would tend to agree with Ant  
that the tutorial would probably provide a better basis...

Ok so if we do this what would be good features to add or things to show?

>From the perspective of the Tuscany Geronimo integration some things that
would be good to show could be:

 - show non-JEE contributions deployed to the Geronimo SCA domain. So that
would be contributions either providing services or wiring JEE artifacts.
For providing services it right now only support implementation.java so it
might be good to add support for another implementation type like spring,
bpel, or scripting.

- one of the focuses of the integration work so far as been in the web
container so a webapp frontend seems appropriate, so using a mix of  SCA
annotations on JEE artifacts and also it would be good to show one of the
Tuscany extension like JSONRPC, though that extension isn't yet integrated
in the plugin so we'd have to do that.

- I guess as its JEE some EJB would be good, so perhaps showing the SCA
@EJBRef rewiring capabilities on simple non-SCA EJBs

Any comments on that, and does anyone who know the tutorial application well
have any good ideas how it could be changed to use those type of features?

+1 for extending the store tutorial with JEE features. The store tutorial
doesn't show this or other things that have been coming on-line recently
like JMS. So it would be good add some new scenarios that show these new
features.
