Thinking of getting an Afrocarpus gracilior, but the only ones I'm seeing are already three or four feet tall, which seems like it'd make them difficult to take over to a sink and water. Also they probably get heavy when the soil's fully saturated (And A. gracilior's seem fully capable of getting pretty large indoors, compared to P. Macrophyllus which gets *bigger* but stays fairly short and bush-like).
So I guess my concerns would just be weight of moving it around when wet and getting the soil flushed when you're watering it.
I'm not sure if that'd work well. Pododcarps don't seem to respond as well to stress as angiosperms do, as they're fairly slow growing indoors and don't really re-leaf readily without heavy pruning, and the ones I'm looking at are fairly established soil-growers.
I don't lug any of my plants, even the small ones, over to the sink to water unless they need a shower or something special like that. (I'm pretty much in a wheelchair, so I try to be efficient) Instead, I have them standing on deep gravel trays (I try to find trays deeper than the standard 3/4" or 1" ones, so I can really flush the soil when I water and still have the water in the trays be below the top of the gravel. I figure it has the added benefit of helping with humidity. Maybe that would work for you with this one.
Here's a picture to illustrate my complete lack of self control :) I need to figure out where to put this thing.
Anyway, I thought about what you said in regards to the drainage tray and pebbles. I'm thinking of modifying that idea into having an entire large pot filled up with pebbles. This creates more drainage area and give the tree a boost so it can get more light on the lower branches.
