>When you work over Windows Terminal Server, only keyboard and screen info is send over the line. So, I'm at this virtual machine, and in there there is a Browser icon. That connects to internet, so my virtual machine has the normal internet connection, and I am (at home) getting the screen-pixels only, i.e. at home I didn't start any browser.

Well, in that case, there isn't that much I can do. You are being slowed down by your own way of connecting. If it would be that slow we wouldn't have that much traffic here and I would be bombarded by emails. :)
