I consider data about the transaction (such as when it happens, the
amount, and from who to who) sensitive as well.

And chat messages. People have sensitive conversations sometimes, and
many people can only contact each other through SL.

So there are going to be people there doing things like sending
passwords by IM.

So, my box can do aes-256 at about 90MB/s on one core.

I don't think I've seen much more than 300KB/s normally, so that's about
3ms. For the viewer it's really insignificant.

Of course it's a lot more significant for the sim, but the average
amount of data being transferred should be well below 300 KB/s per
agent.
