Geronimo will take care of users' applications and provide run-time environment. Anyway, we will recommend users to adopt GBean usage for Web container configuration instead of using server.xml, which we can demostrate the up-sides of Geronimo architecture using app-per-port sample;
The only reason I can see to configure a tomcat server using gbeans rather than server.xml is if you have a legacy server configuration that you don't want to convert. In my view using a server.xml is a lot more convenient than the individual gbeans.
As for (2), users can simply copy their server.xml into /var/catalina by overwriting the one in Geronimo, and for example, user need to copy the applications to /var/catalina/web-apps/. There would be nothing different from the old days. Geronimo will provide run-time enviornment.
I'd really prefer that we emphasize server assembly using geronimo plugins rather than manual file copying. The two ways I've thought of so far for setting up a tomcat server is by replacing the tomcat plugin we ship or by unpacking a server.xml from a plugin to overwrite the server.xml we ship. The second method seems unreliable to me, what happens if you deploy 2 such plugins?
I haven't checked but I hope that tomcat hot deployment doesn't work. IMO web apps should be deployed using a geronimo plan basically as they are today. If copying an app into a tomcat hot deploy folder does work, the result won't relate to geronimo services in any way (for instance jndi, transactions, security).
In either scenario, users' apps will be untouched and cann't be used as geronimo plugin because they are still tomcat-specific.
Web apps should still be deployed as plugins using a geronimo plan. Otherwise they will not get any benefit from running in geronimo rather than plain tomcat: they won't have access to geronimo jndi, transactions, security, ejbs, or any other services.
At the moment we don't support context.xml files. It would be great if we did but that would require quite a bit more work.
Anything incorrect, please hop in.

IMO our way of configuring the tomcat server using server.xml is working fine and the main remaining bits are really documentation. Since I am terrible at documentation I hope others will take it upon themselves to help with it :-)
I'd like to see
-- a list of stuff that doesn't work in geronimo. My recollection is that the main things that don't work are configuring jndi (such as deploying datasources) and realms (this might actually work, I'm not sure).
-- at least one sample of how to use it. I think a good starting point would the the app-per-port sample that shows how to have 2 web apps each exposed on a different port. This requires setting up 2 entire tomcat servers and I think would be a nice example of the simplicity of the server.xml configuration compared with the gbeans we used up till now. I think I'd consider deploying the server.xml in a plugin that completely replaces the existing tomcat plugin.
