The problem with mods like this, is they seek to do what other mods have already done and so their popularity relies solely on a narrow fan base. As such, too many other popularized mods are gaining momentum right now (ic2, buildcraft, thermal expansion, thaumcraft, etc...). Once the textures for those mods are fleshed out, someone may be able to dedicate a chunk of time to this, but it really comes down to practicality for the texture-er. Most artists on here, only texture those mods that they use - that's just the reality.
I feel like dartcraft is a little late to the party, in terms of viable functionality compared to the mainstream mods that I've already mentioned.
To address some misconceptions... Sphax does
not texture mods anymore, he's too busy with other projects and keeping the base bdcraft texture pack up to date. HanFox is already at capacity with nearly, I'd say... +/-50% (loose approximation) of the mods being textured here, but there's a small chance he might...
As far as someone "needing" to take over; that's entirely subjective. I would suggest that there are other more popular mods which need tending to before this one, but that's my opinion, as it is your opinion that this mod "needs" to be textured. Desperation for textures is like a tree falling in a secluded jungle; if there's no one around to hear it, does it make a sound? (metaphorical)
This thread has now been bumped 3 times this month with no responses for being taken over. I'd say the tree made no sound... at least for now. Please be patient. If someone likes this mod enough, it will get done.
