I fully agree with you, and have considered this option!
I had a look at an implementation for the ext3 as native windows fs plugin I
found somewhere on sourceforge, but then had the strong impression that I
couldn't manage this complexity in the time I have.
On the other hand it was my first attempt to dig into file system architecture
in general, so I wanted to keep things simple.
However, there is no reason why such a native support couldn't be developed
from the current code base.
As solved a few Windows 7 related issues, like permission right
setting, access to physical drives not published by the windows drive
management and strictly separated the Total Commander functions from the core,
reusing the code should be easy.

Actually, I just wanted to have some feedback on whether there is interest at
all, and whether there are people with more expertise to support it.
