I'm hoping that maybe Remi can chime in on this question.

One other option to investigate: Write a small Windows/Wine device driver that 
registers the character device and forwards it to the Unix device node. If you 
get that working you shouldn't need to modify wineserver in a very device 
specific way. In theory the API is also stable (Wine just implements the 
Windows driver API), so the Windows device driver can live out of tree.

See dlls/*.sys for some examples of existing device drivers; In particular 
mountmgr.sys, wineusb.sys are examples of drivers that talk to both the 
Windows and Unix side.
