A nice idea, and I do like the static veil thing, but I have a problem with the team work sprites. If I were the GM, I flat out would not allow it. I have looked over the team work rules, and it is missing a simple catchall phase, "If it makes sense". You should not be able to use team work for all actions. If you want Fred and Charlie to help you shift the so and so, that is fine, but if a jeweler wants to cut the perfect diamond for an engagement ring, she can't get bonus dice from the four assistants helping to hold her hands steady. I view matrix actions as running algorithms on your deck, or techno brain, and then applying code or resonance to the task. If two different hackers were both running algorithms to crack the protection on a file, you don't have team work, you have a race. One hacker may hit the code key before the other, but they can't combine algorithms to run better.
If you are wanting to use sprites to stack up unlimited bonuses on a roll, then compiled sprites can add their ratting to a threading test, and this isn't team work. You could have five sprites assisting the one threading attempt. You would still be limited to the ratting effect of course, and they can't help with the exceeding high drain you would suffer (edge at rating one), but it is legal. Nothing in the rules prevents using more then one sprite in this fashion, but it probably should, and I want TM's to be more powerful.
As a side note, even if the team working would work, a decker could do the same thing with 4 agents, which have all the skills you could want, and don't use up services.
