Will Liberty support the java:app/ JNDI namespace for embedded data sources and other stuff?

Stop spreading FUD, you filthy weasel. Things like TomEE, Resin and yes even Liberty -are- lightweight by pretty much every definition of the word. TomEE for instance is 25mb total, starts up in seconds, runs in 64mb of memory and has an elegant and simple programming model (eg not a single line of XML configuration is needed, a simple web page with backing business logic can be setup in minutes at most, etc).

It absolutely rocks that you are working towards an official web profile implementation, but what about the next step? Having a Liberty Full Profile? Is that a goal for Liberty?

Currently if you need the full profile (like for eg JMS, or @Asynchronous, etc), you still need the full WAS, but then you also get the "large-scale admin capabilities", which as a developer I don't need.

This sounds better than the steps your teammate Tom listed above. Is the "server.bat (server.sh?) create" step already optional?

Awesome! :D
