Broadcast video + field rendering: How to?

OK, stupid problem. As we all know, broadcast animation is actually double the nominal framerate (normally 25 fps for PAL, 29.97 for NTSC) due to interlacing. So for optimal results animation needs to be 50 fps for PAL or 59.94 fps for NTSC.
Do I actually have to render that many frames, or is there a smarter way? And don't I need to do the interlacing myself?
I know this should be obvious, but I'm having a slow day...

Well, you could split it into 2 steps. First, make a computer friendly animation, then run it through something like AviSynth to get NTSC or PAL footage. If you wanted to make a nice NTSC animation, you could do 60 fps at half height, which would give you your 30i fps.
FYI: Animation is usually 24 fps, then telecined to 30 fps, and I don't know how they do animation with PAL. I know the easiest way is to just speed everything up to 25 fps.
