In the patch I sent you, the interception is made on the client side. By 
transparently, I meant the obfuscation/deobfuscation mechanisms.

The full discussion we have is around passing console handles to the 
server. The client already intercepts any handle and checks whether it's 
a console handle or a regular ntdll handle. If it's a console handle, 
then implementation is passed to console functions (ReadConsole for 
ReadFile and so on).

The discussion we have (at least as I understand it ;-), is whether we 
should manage, on the client side, console handles:
- as obscure values passed by the server (except for the two low bits 
set to 1) (this is the current patch implementation)
- or as regular winserver handles with the two low bits set to 1, which 
means cleaning up those bits before sending the handles to the server

the transparency I was talking about referred to how the client should 
manage the handles if we had to move console handle creation out of
