If you're using Linux then it's pretty trivial to try it out; just download the latest SqueezeCenter from SVN and apply the patch. On Windows it's more difficult because you have to install a Perl interpreter, but it's still doable. Also note that on Windows you must use the wvunpack.exe that's in the patch because it has a little mod that allows it to be syntactically identical to the Linux version (it ignores -o on the command line).
Here's the forum discussion at Slim Devices
Here's a link to the entry in their bug database with the patch
With perhaps a little encouragement from HA members, I am hopeful that Slim Devices will get this into the nightly builds soon.
