The CVS Head now has more field types, more validation rules and a way to do a getAllSorted for a contentObjectType. Once I figure out some basic filtering I'll release as 0.2. I may also hold off until we implement multi-value fields and complete SELECT boxes and multi-checkbox Form elements.
The first release is now out, version 0.1. However, if you are interested in seeing the latest we strongly suggest you use CVS to check out the latest work. If you are a Windows user unfamiliar with CVS, check out TortoiseCVS.org for a great GUI CVS client.
