Sorry, the elusive Pacemaker portable DJ gadget isn’t here yet, but an online DJ portal is. Coupled with a free PC/Mac music / mixing editor, the web site allows you to create your own mixes and share them with the community.
Tonium has apparently done deals with a number of international music publishing houses, so the resulting service should be fairly watertight legally.
The free software is cool to use on its own, and it looks ready to integrate with the Pacemaker hardware when it becomes available.
Give it a go — even if you never get your hands on the Pacemaker, the software is fun to use and there are some interesting mixes already in place on the web site.
