A Familiar Tree, Variations of Ally Spirits Options

[Friggas Ring]

I was reading Steve Kenson's article of variations of Ally Spirits when I thought, "I wonder why no one has through of having an Ally inhabit a great tree."

Let's say, sitting in my shaman's backyard is his Shamanic Lodge, and smack in the middle of the lodge is a huge oak tree taller than the closest house. It may not move, but it can see for miles. And just how many times do you worry about the trees when your team breaks into someone's house? It could still fight in astral space using its sorcery skill. It wouldn't have any quickness, but its body should be through the roof. Sure, it can't come with you on a Shadowrun, but it can guard your stuff while you're away or asleep or just not paying attention to that small team of hitmen sneaking toward your kitchen ready to unleash Hell on you hoop because of that hit on Renraku you pulled last week.

If anyone's tried anything like this before, let me know how it's worked out. Also, if you foresee any problems with an ally inhabiting a tree, let me know. I may bug my GM to let me do this in the near future and I'd like to address any issues beforehand.
