@Angelone; It might just be me, but your first words made me think of Ask That Guy's catchphrase.

That's a compliment, at least IMO.
Thanks for the compliment.

It's an interesting point to me, and; the books are a little contradictory on how harsh the authorities are about SINs in public areas, but getting into an Embassy, even officially, is never easy. I can see it being a battle for someone SiNless, especially a Parahuman. (Pixie, FTR, so the only Embassy she can go with is the French... and there isn't one in Seattle

)
Still, it's an interesting point. If your SiN is stolen, and then 'Updated', can the thief just get away with anything under that SiN? I guess with a commlink and an established life in the area, you could lodge a complaint with more local authorities. In Seattle, either your local Corp office, KE, or the Metroplex Administration. If gone for a while, someone in another country could do so on your behalf. But if you're a traveller, with no known relatives.. (and a meta/para, and thus going to find it hard to deal with the authorities)
Plus, with no commlink, you have no money, and can not get a commlink to contact others, correct?

(At least, not easily)
