Vista - Tracing Cmdlets and providers

Is there a way to hook into the Set-TraceSource/Trace-Command infrastructure
so that our Cmdlets and Providers can output trace information?

PStracesource , is a public class on system.management.automation , as
is as is PStracesourceoptions enum so i don't see why not.

and it uses the standard dotnet tracing techniques..
i.e with this attribute
[TraceSource("Mycommands", "Sometext")]

....

static PSTraceSource tracer = PSTraceSource.GetTracer("Mycommands",
"Sometext");

and using this pattern

using (IDisposable disposable = tracer.TraceMethod())
{
}

If you get anywhere with this, we'd love an example, i haven't
bothered messing very much with it as of yet.

PSTraceSource is public but, the constructors and all of the GetTracer
methods are internal. I can't figure out why some of it is public but, it
appears, not enough to be useful.

I expected the base class of PSTraceSurce to be TraceSource but, it isn't.

That's what I would like to do but, GetTracer and TraceMethod are both
internal.

At this point, I just want to be able to spit out text when the user does a
Trace-Command that invokes one of my Cmdlets or Providers.

hmm, well you can maybe build your own wrapper class and use
reflection to get the internal methods. very hacky though
