I'd hotpatch all Winsock functions.  Patch the prologue; do not patch
the IAT - this is not enough!

Detours are pretty much the easiest and most applicable means to achieve
traffic redirection in user mode.  Unfortunately a hostile application
can easily defeat ordinary detours by bypassing Winsocks or loading its
own copy of the Winsocks dll.

Filter drivers, anyone?
