Thanks for that, Toady. Good to know that its all possible.
I remember reading somewhere that a channel acts like a tile one level down, so is that how it works? The main concern that I have is that the moment I tell my dwarves to start pouring the water in, it will hit the channel..But then again if I dig out the tile underneath the channel then it would probably become a pit..Which leads to the question: "Would digging underneath channels destroy them? And if so would it be a good idea to have a new designation 'Danger' which is automatically applied to tiles where it would be unsafe to dig into (I.E into a known magma flow or underneath a channel)?"
I reckon it would be a good idea..

Also, about what you said with regards to the vertical-moving construct?
Here's my take on it.

New Building: Shaft Harness (Name subject to change)
Requires: One unit of building material (I.E Block, Log, Metal Bar, Etc), one Mechanism and one unit of rope/chain for every 2 levels you want to have accessible.
Mockup:
code:
......R\........

So you have the building (R) on the edge of the pit with the dwarf attatched to the rope harness.
How it works:
After building your harness, you can use the designation "Mine Shaft" and a miner will automatically jump into the harness and start digging down. After you get down to the first level of depth the harness will act moreorless like an elevator for the dwarf that is doing the digging (I.E he can move up and down to where he is needed and even get out of it for a bit to dig a corridor).
Heck, you could even make it so you can stick a mason in there while he makes his carving "Ulofrisp - The Steel Tips of Pointing. This is a well designed images of spikes and Goblins. The Goblins are impaled on the spikes"
Anyhow, could you please think about this one?
