Subject Re: Car plugin is fighting with maven too much

Now that sounds promising.... using the existing geronimo-plugin.xml and 
deployer to install new apps without having to build a car wrapper for 
them.  That would make it tons easier to create "remote install 
descriptors" for apps like Liferay, Roller, ....

Would we just extend the application deployment plans to allow for a new
