Sorry for the late reply. I've been on a deadline at work for a large site :-) Scaling is a good question. But I think in the near future we'll start using service to the degree they and Java were created. Talking appliances, machines, etc. through the net. Hence the big need for security of course. Also once IPv6 is implemented on a wide scale, we'll see the net take off yet again. But thanks to MS OS's it might be a little while.
