The native XACT APIs have added the support for programmatic wave playback. I.e. at runtime, you can load *.wav files into a Wavebank and play them from there, without needing to create a project and compile the binaries.  This is something we're looking at supporting in our next release, but I want to gauge how much interest there is in this feature?  Keep in mind that implementing this feature may very well mean we can't do some other feature.

So how important is this to you? Is using the XACT editor and precompiling your audio a big issue? Is it just a learning curve for the editor, and then you move on?
