Probably far too late, but maybe this will help someone else...

1) Create a hole that's 3 wide.

2) Put a Hellforge in the bottom of the hole.

3a) Drop one (1) bucket of lava in the hole, if you want water dropped into the hole to vanish.

3b) Drop one (1) bucket of water into the hole if you want lava dropped into the hole to vanish.

Explanation: Obsidien can't form in on a block that contains a hellforge, so when water lands on top of lava (or the other way around) the top liquid vanishes, and the bottom one remains.

Note: You can put in more than one bucket full of the "priming" liquid, but if you put in too much it won't work. Finding the exact amount that's "too much" is left as an excersize to the user. :P
