1. Getting off the ground should be easy. There is a low level filesystem 
abstraction that will need to be implemented using NTFS semantics. For an 
interface definition see:
http://cvs.sourceforge.net/viewcvs.py/dirstorage/DirectoryStorage/BaseFilesystem.py?rev=1.14&view=auto

For an example implementation using a posix filesystem see:
http://cvs.sourceforge.net/viewcvs.py/dirstorage/DirectoryStorage/PosixFilesystem.py?rev=1.23&view=auto

(in principal this doesnt need to be implemented using files and 
directories..... If anyone ever have a hard "data must be stored in oracle", 
or "data must be in COM structured storage" requirement then this route is 
likely easier than writing a storage from scratch :-)

2. Some of the peripheral tools might make some light unix assumptions, but Im 
sure they are all fixable except.....

3. The replication tool is unix-heavy. it uses fork and exec.
