Yes, I had rethought about the idea after posting that post and you will have to be really careful that the mass of the tomatoe vine when fully laden with tomatoes does not pull itself out of the pot. Other than that, it looked like a great idea.
i think it should be ok - it's a super sweet 100 plant and the exit hole is less than half an inch. i saw some place once selling specialized planters for just this kind of thing, but i just tried it with a discarded hanging basket.
