They're freely distributable in binary form, but they link against various MSFT 
libraries which have licenses that restrict what can be done with the source. 
The binaries pass all the MSFT class-specific WHQL tests and are signed so you 
don't get annoying pop-ups when installing them.

I'm not aware of any relative benchmarking having been done, but it would 
certainly be  interesting to know.
