I can't comment on whether MPLAB-ICE works on NT or not, but I would point out that using the Parallel port with a custom protocol does NOT PRECLUDE running on NT. It just forces the developer to write additional code in the form of a ring 0 device driver. We have several products that use the parallel port under NT with custom protocols.
