Hi RabidSimian,
I got your PM and decided to do a little write-up on
N. campanulata here. I'd like to say that I'm moderately successful with this species.
This thread is a good starting point for more information.

I grow mine lithophytically for aesthetic reasons on a large chunk of limestone rock.

This is a picture of it the last time I had access to my camera, circa two months ago. I have two separate clones growing on it, a red clone and a green Borneo Exotics clone. This is definitely not the easiest way to grow
N. campanulata in my opinion and
N. campanulata is not a beginner's species, nor very forgiving. Here's some abbreviated pointers about what works for me:
- Bright light: this one's fairly obvious from the full tank shot.
- High humidity (65-70% +)
- Good ventilation: I run a computer fan in the tank intermittently for air circulation
- Airy medium: should have plenty of aggregate (50% +), be it pumice, pouzzolane, akadama, perlite, or bark
- Moist but not overly wet: I let mine dry out more than the average Nepenthes in between waterings
- Temperature is of less importance, room temperature is good but lower than 10 C and higher than 32 C should be avoided.
The environmental conditions are very dependent on your growing conditions of course; keep a plant wetter and you'll need more water retention (sphagnum or peat), etc. However, I see some potential caveats to keeping them with frogs.
N. campanulata in my experience does not appreciate much misting at all and doesn't like extra water in its pitchers, as well as needing excellent ventilation -- it really is a more 'dry environment' plant than typical lowland
Nepenthes. Also, I could imagine that in larger pitchers, smaller dart frogs may not be able to escape if caught as the pitchers have exceptionally waxy sides.

I have never tried mounting
Nepenthes on driftwood, but I think that a spot in a typical frog tank is more well-suited towards orchids and bromeliads. I'm not sure whether the roots would take well to it or not, and if it were to dry out too much without having much root space (and therefore roots), it may wilt too far to save.
