I didn't answer your question because it wasn't worth answering.
Then kindly explain why I, 12,000km away, can use Webnet with no appreciable lag?
12,000km is meaningless. Physical distance means nothing on the internet. The distance between servers (hops) is what matters. For example, I live in Pennsylvania, USA. I'm about 4 hops from England, where as I'm about 8 hops from Texas, USA. So geographical distance is irrelevant.
As for the last part, how should I know? I have no idea how Webnet works, if you can get someone from Webnet here to describe their system than fine. I told you the system I can up with would be lagged, perhaps they are using something I didn't think of. But you have provided no technical specs about their system, so how am I supposed to comment?
