Possible for G to directly consume a Tomcat server config w/o changes?

[Bill Stoddard]

I know G can't consume tomcat configs today, but is this a feature that 
could be developed for G 2.2?

Say I have an application successfully deployed and running under 
Tomcat..  wouldn't it be nice if I were able to drop the tomcat server 
config into a Geronimo-Tomcat assembly, start the server, deploy the app 
and be up and running in seconds.  I'm talking about a seamless, zero 
effort/zero touch migration from Tomcat to a Geronimo-Tomcat assembly.  
Is it possible?  If not, what simplifying assumptions could be made to 
'mostly' achieve a zero-touch migration? 

What are the primary challenges with consuming a tomcat config unchanged 
with a G-Tomcat assembly?  Same Q's apply for Jetty... what's 'doable' 
with-in reason?

Thanks,
Bill
