The announcement is late, but:
v0.1.1 is released, with performance improvements and a deadlock fixed in the cache purging code. Tested on Mono, VS2005/MS .NET 2.0, and VS2008/MS .NET 3.5
v0.1 was also released recently too.
The project is now active. I've committed the project in its current state to SVN, it compiles on at least .NET 2.0 and Mono, and is usable under .NET
