There has been quite a lot activity on Virgo CQs. Many have been approved but some need more work.
Contributions are starting to come in from the community, notable on the snaps prototype.
I am writing up more detailed coding guidelines on the Virgo wiki for the benefit of contributors.
There has been discussion of Maven build on virgo-dev. This is progressing but there seems to be a different philosophy for dependency management between components. In Maven, everyone normally gets to use the latest version of everything, within a certain version range. In Ant/Ivy with Virgo build, changes need to be promoted explicitly, which is more conservative.
