Hi all,

I actually looked at this a year or two ago.  It's not an unreasonable
amount of work that has to be done to support reparse points, but it's
certainly not a trivial amount of work; I had to dig through quite a
bit of Microsoft documentation just to get a handle on the problem
space.  You might want to ping Richard Sharpe (I'm CCing him) as he
was also doing some work on this a while ago, IIRC.
