Does Wippien use a direct connection?
I started using Wippien to make p2p connections between 2 distant Windows Servers. I use 2 different GMail Accounts. 

Wippien uses "Mediators" to initiate the connection. But are mass data transfers really direct, or is it routed through the mediator?

I also found this article which seems related: http://stackoverflow.com/questions/44205/direct-tcp-ip-connections-in-p2p-apps

How can I find out if the connection is direct and how can I find out about speed?

The connection seems slow while I transfer files, but this is not measured but only my first impression.
