LINQ to WMI provider

Recently, I needed to analyze WMI-related code and now, I really think about to implement\find\improve a LINQ to WMI provider with the following requirements:

1. 1. it should support both .Net 2.0-3.5 frameworks
2. 2. it should be extensible - as WMI support providers model LINQ to WMI implementation should allow people to quickly create modules for different WMI providers
3. should support querying both events and objects
4. should have Castle-like error handling

So far, I found only one implementation of LINQ to WMI here and here.
Should take a look at what is implemented already...
