Like Ean said, "many industry peeps read this"
"What I really want to see in terms of standardisation that will help us is an industry standard audio interface, pay some licensing to serato, and create a club level 4 stereo channel interface that can be permanently plugged into the club mixer. The key to its design would be allowing two laptops to plug into it at any one time, and each channel would have a selector knob to set which laptop it is running. This would allow seamless change over between serato/traktor/VDJ etc and is totally possible today (cept maybefor the getting Serato onboard part)"
