I would make a jig that was about 2' long, the width of the pvc, and with
a top that is just higher than the blade height. Then you could hold it
on the table and feed it through. with it 2' long, you wouldn't have to
hold it above the blade. (yikes)

That would work if the blade is high enough to cut the pipe in one pass. If
not, you have to get a tad more sophisticated. I'd make a jig like you
mention for the first cut. Then I'd take a strip of metal and bend it 90
degrees to act as a guide while putting the pipe through on the second pass
that splits it. The guide can be ahead of the blade and would keep the
tubing from turning as you push.
