I never said it was going to be easy, just that porting for win32 requires some win32 work as there are substantial differences between linux and win32 (duh). They managed to get php win32 thread-safe after all.

Setup nginx as a front-end, make a pool with nginx back-ends (just like you would do for fpm with sockets or tcp) and from there on the back-end nginx servers are load-balanced from the pool front-end just like fpm would work, nothing magic about it.
