You can teleport lava from the nether, I'm doing it right now. You just need to set down a Teleport Tether (perhaps other anchors work too) at the pumping site. This keeps that area loaded in memory. It's a good idea to have one more tether at the receiving station as well. Pump the lava into a series of magmatic engines  and they just dont stop. I THOUGHT the lava would be used up in the Nether, slowly, but so far none of it is going away...not that I'm complaining.
