iXsystems has uploaded a snapshot of their new FreeBSD 8.1-based FreeNAS.
This snapshot is for developers only. It is not functionally complete yet, and there are likely many rough edges.
If you are interested in playing with it you will need to download the code and build it yourself. You can find the code in SVN and here is the accompanying README.
The new FreeNAS is based on nanoBSD and builds for 32 and 64 bit machines, but building a 32 bit image on a 64 bit installation is currently broken.
