Oops I didn't see your reply and went ahead with coding...
I hope you don't mind :D

What it does :
It checks if winamp is playing a song when you start BSplayer
If it is, the plugin will pause winamp.
When you close BSPlayer (the normal way) it will check if winamp is still paused and resume playing.
If winamp is in any other state, nothing will happen.
This is a first version. Quick and dirty.
As always all feedback is appreciated and will be taken into account for future versions.
Enjoy,
Rafke P.
