So you propose to take:

		<Menu>
			<Name>VideoPlayer</Name>
			<Directory>suse-multimedia-videoplayer.directory</Directory>
			<Include>
				<Category>Audio</Category>
				<And>
				<Category>AudioVideo</Category>
				<Category>Player</Category>
				<Category>Video</Category>
				<Not><Category>X-SuSE-Jukebox</Category></Not>
				</And>
			</Include>
			<Exclude>
				<Filename>realplay.desktop</Filename>
			</Exclude>
		</Menu>

put VideoPlayer as a category in the applications table?  I suppose that
would work, but when it comes to displaying, you'll have to stick it all
in memory anyhow.
