Torque network engine overview?

The book "3D Game programming all in one" does a good job explaining the Torque engine, but I'd like to know some more details about the network engine:

1) Did I understand this correctly: Torque has some internal way to use server/client variables... datablocks are they? I mean like: if some player picks up a powerup bonus (client checks "increase my health") it is possible that the game has a datablock where it says that "if client increases powerup, then server and all other clients will increase his powerup automatically"?

Example:
- Player A: increase stamina +1
=> this is automatically send to Player B, C and D

Can you tell me if this is correct, or am I totally lost here. I would like to see a small example on this?

2) Does Torque use TCP or UDP protocol (or both?) to handle network traffic? Basically I'm just curious :)

3) How does Torque handle player movement... I could not see any info on the book about this (well, I have not finished it yet ;)) - where does the player info is sent... or is this again one of the (nice) in-built systems that Torque has?

4) What are those thingies that book showed:

Quote:
GameConnection::EatMySorts()

Are these related with question #1? Are these like methods of GameConnection object?

5) I heard there is some (outdated) Torque article on these sites... I could not find it. An URL would be appreciated :)

Thanks again folks.
