Jim, This is known as http://trac.osgeo.org/gdal/ticket/5695. The restriction has been put, because currently the driver couldn't not produce correct RGBA files with the alpha band correctly marked as such. I may have the opportunity to work on that in a medium term. In the meantime, you could perhaps try the opj_compress utility of openjpeg ( https://code.google.com/p/openjpeg/wiki/Downloads?tm=2 ), but it will likely has the same flow as indicated above if you're interested in RGBA images.
