I'll try to find it, then adapt it and send it to You in private first, 
but this will take some time!

Download the complete Ghent Output Suite. It has several examples with 
Separation and DeviceN colorspaces with spot colors (that samples I also 
used to test the DeviceN implementation in level3)
If that works, I can send You a few additional PDF in private which uses 
spot colors.
