Intermedia is probably the most likely. I know there are few people growing them over there and there was also quite a bit of seed going around a few years ago. I haven't seen nidiformis mentioned too much on the forum.

Many forms of intermedia are swamp plants and can take water to the top of the pot during the growing season. You just need to make sure that the water in the tropics doesn't heat up too much and cook them. The method Tarence has mentioned of morning sun and afternoon shade should stop the overheating as would using a large container.
