There is no problem Fuse in Linux systems , but in windows really it is problem because we can use only 15 trial day (sometimes they cant send key i mean : eldos) also if we want use always ; must pay for it.
That why i searched callback filesystem for windows (opensource)
Dokan - http://dokan-dev.net/en/ - it have many library .net - ruby and other.
fuse4win - it can found in github search
davfuse - it is supporting many system xp,win7
have a nice days
