Yeah due to the fact that a null sink has a null monitor, this module is of limited usefulness, but I think it could still be useful in some cases where you do want a null recording but don't want it polluted with sinks. I did actually have someone that wanted to hook up null sources and null sinks to some Windows VMs a while back (several VMs but only one null sink+monitor source). He was annoyed that he could record other VMs output from within a separate VM on the monitor. Obviously he can shuffle around the various streams and create multiple null sinks but it would have actually been simpler to setup a null source in the first place. So I'll do some testing then grab it at some point (tho' need to spend some time reviewing Margarita's work before next week otherwise Liam and Mark will find some way to punish me!)
