Yeah, like Togo shows, when you invest in a sanctuary, its sort of like renting a seat at the stock exchange.  As long as you hold the seat you receive the privilege of voting on governance issues and receiving a monthly reward (approx 10% of the cost of the seat comes back to you in revenue per month, roughly, depending on how many sanctuaries exist).  The escrow amount is still in the air, West is doing some simulations on that.  Its probably between 600,000 and 1 million BBP of escrow.  The escrow provides a useful service - to allow us to offer instantsend - that means coins can be sent from point a to point b instantly.
