Errrr ok then, why can't spirits grant their immunity to normal weapons to people? Why can't you use mana spells on purely physical targets? Because the targets for the action are specifically laid out int he rules. This power specifically lays it out to target technomancers. Lets compare it with some other language for sprite powers.
Similar deal, if we open this up to the "words are just words" interpretation vs the "words are rules" inteprtation tank sprites (and spirits for that matter) should be able to pass on the hardening or immunity to normal weapons powers on to casters (which they can do through possession but that's a completely different ball of wax and a small part of why possesion is silly)
This is a poor example.
Castling has an effect that specifically targets it's Compiler. The Hardened Armor power does not target anyone else, it's an innate ability of the Sprite/Spirit.
If the Sprite can use the service on it's Compiler, it should be able to use the power on any ally, the same way a Spirit can use Guard or Magical Guard or Movement. Assuming, of course, that the target is active in the matrix. Obviously, Castling would be useless on a Mage with no matrix connection.
My point about te wording was not to get caught up in the fact that it specifically says "Technomancer".

Basically yes you can designate your sprite to perform services for another person and they will do so to the best of their ability, this particular power can only be used to transfer damage from technomancers nothing in the rules change that. Just for comparison's sake lets look at a power that they explicitly mentioned could apply to others.
Here we have another power from the same section where the targeting parameters are specifically left very wide. I must conclude that there is a reason for this and a reason for castling to be very specific. I love TM's as much as the next guy but castling is already prone to abuse and funny interpretations without loaning out paladin sprite bodyguards to every matrix user beyond their original scope.
Not everything is written well, and not everything is written in a way that describes it's intent. I also don't see Castling as being all that abusive, since so little happens in the matrix, and so few characters actually interact with it in a meaningful way, allowing the Hacker/TM to do most of the heavy lifting.
(This is also why I'm honestly not a huge fan of Technomancers. They're incredibly wonky and not really well thought out. I'm also not a huge fan of a lot of SR4's Matrix rules. The base concept of AR is sound, but the rules themselves are seriously kludged together, and Unwired built upon a very shaky foundation, since it wasn't designed to rewrite the core mechanics any).
ANyway, like I said above, this isn't a ruling, just my off the cuff answer. I could be wrong.
