OpenVPN Configuration for protocol TCP vs UDP

So when you set up a OVPN server on a Mango, you have to choose TCP or UDP. The OVPN standard allows adaptive, where you initially connect TCP and then upgrade the connection to UDP if everything is going fine. Is there not a way to use this with a Mango. I want to use UDP, but am concerned that the initial negotiation of connections might be better on TCP. Ideas or thoughts?

Is this right? I thought server had to bind uniquely to a port and protocol.

No.

Adaptive first tries UDP and only uses TCP if the UDP connection fails.

Yes, but only on the client side, and only in the paid version, I think.
