I took the liberty to create my own template consisting of a multimodule build:
Flex module - looking prettymuch the same as Per´s.
War module - depending on the flex module wrapping the swf file into a war ready to deploy.
I would have created a maven archetype, but considering mavens lack of support for archetypes containing multimodules I just created a zip.
I find the template useful when starting a flexproject from scratch and maybe you will too?
