What you could do very easily is make a dual boot machine with both WinMCE and LMCE if you are not certain yet.
I did with a 60 day trial WinMCE, but dumped that on the second day.
I did like it's way of locating shares better though, just navigate and select the appropriate folders.
Then again, there's no "auto" anything and too many restrictions about what you can share and not...
(The Xbox 360 woun't even see network shares mapped by MCE... arrrgh, well, LMCE for me)
