I don't know if this could help you out but Resolume sends this OSC information (by default on Outgoing Port 7001):
/layer1/audio/position/values : <OSCVal f 1.000000>
/activelayer/audio/position/values : <OSCVal f 1.000000>
/activeclip/audio/position/values : <OSCVal f 1.000000>
where the float is the position of the playhead on the timeline with f=0 is the In point and f=1 is the Out point so if you know the duration of the clip, you could infer the clip time remaining info pretty easily but I don't believe Resolume can send any of the clip metadata for you to do it automatically. Keep in mind that the In and Out are not absolute so the information will be different if you modify the In and Out points.
