I used GSPlayer for a while on an SD card using WIFI access. The only quirk I found was the skins had to be in their own folders in the root location of the Storage Card (i.e. /Storage Card/Kenwood Skin/*.*), I couldn't get the skins to show if I placed them in any folder deeper than on 'layer' on the card. Since I did this, I placed all of the various radio station shortcuts in another folder on the storage card as well. It worked flawlessly for the time I used it. I'm now using Today Player (I like the today plugin interface) but haven't tried any of the shoutcast shortcuts yet.
