I could really use a window independent of VS2012, that I can run on my other monitor, to show TraceSource messages as they are written? I realise this complicates things slightly being cross-process, but I'm sure there are many ways of just sharing data between processes, including in-memory, and at worst on-disk, databases. The data only has to be persistable in the listening app, so maybe even an in-process trace listener that uses Remoting calls to the listener dashboard app.
Or is there already something I can do this with?
