The only place I've seen it was on q3df.org, so probably not.
It's not that great though; it needs a lot of tweaking before it's really playable. They're not portal-like enough imo. They're more like portable teleporters that save your speed (they aren't smooth at all, and they're buggy).

oh, im a bit sad to hear that cause i dont expect a major change of how the portal idea is accomplished in that mod. could be some fun anyway if it ever gets a stable release
