Putting a Machine Sprite in a drone Options

[Surukai]

A player in my group wanted to make a "drone-omancer" inspired by the massive success of the technomancer in the previous adventure combined with how unstoppable possession spirits were he guessed that a technomancer with sprites in his drones ought to be at least quite cool even if we didn't expect it to go anywhere near a Pasteel Humunculus (IMG:style_emoticons/default/smile.gif)

However, there seem to be some skills and complex forms missing for a Machine Sprite to be able to operate a drone or have I read something completely wrong?

What a drone needs as bare minimum is:

Software:
firewall, analyze, encrypt, tacnet

"Skills"
targeting autosoft, clearsight autosoft, pilot autosoft

(And response/system 6 to run the 6 softwares at the same time without getting degraded, this can be fixed with optimization program options for a regular drone)

It seems the Machine Sprite can take any autosoft as optional power but to be able to fully run a drone it needs to be rating 9 to not be either blind, stationary or unable to fire and they are still unable to be encrypted unless they are the odd node in the network, making multiple drones with registered sprites rather unsecure unless you use the "technomancers and sprites are immune to all hacking, spoofing, electronic warfare and tracking by non-TMs" optional rules (I clearly don't, it's bad enough they are invisible and have three times the dicepool, why make them immune on top of that?).

A steel lynx and dobermann needs two pilots too, don't they? (Since they have both wheels and legs, should need both Anthroform and Ground craft right?)

Or how are sprites meant to use drones, or are they not supposed to? (Other than say fire the cannon with sprite-dicepools through command alone?)
