The main reason for this proxy is to be able to run some win32-only pcap applications like the

IEC 61850 Demo Software from systemcorp.

or many others like Asn1Browser, Cain & Abel, Gamer's Internet Tunnel,

PacketVB (and PacketVB based Apps), SharpPcap based Apps and maybe coLinux in the future.

Of course non-win32-only Apps will work fully too, like Wireshark, but that's just a cool side effect.
