This is exactly the project which was just starting to be discussed on
freebsd-fs. There are several people who would love to work on this and as
long as the FreeBSD community is going to support. If this project is
going to be supported then it will be done. 

Softupdates is definitely a viable solution however it does not address
several issues and the license is not a BSD license so it makes me
uncomfortable.

LFS is being considered as a starting point for this project. The goal is
to build an extensible file system with features such as the ability to
grow and shrink partitions, acl's journaling etc.

XFS is also being considered as a feature reference.

Absolutely.
