Virtual Distributed Ethernet - CryptCab

 VDE is a virtual switch that can connect multiple virtual machines together,
 both local and remote.
 .
 Components of the VDE architecture are VDE switches (virtual counterpart of
 ethernet switches) and VDE cables (virtual counterpart of a crossed-cable used
 to connect two switches).
 .
 This package contains CryptCab, which can be used to send encrypted data
 over an UDP link.
