It's great news to hear more and more MPEG-4 products becoming
available. Also note that you can download SigmaDesign's 
Advanced Simple Codec here:

As for your license question: the click-through license states 
that the user is  responsible for any license fees. I am not a 
lawyer, so I won't make any statements as to how safe this is.
(but I did download and will install shortly :-)

ps: 	A word of caution about calling a decoder that does not do 
 	1/4 pel and	GMC (yet) "Advanced Simple". At WEMP-4
	it was clear that there are many decoders that do AS
	without something - the "something" being GMC, 1/4 pel 
	and/or B frames. These decoders do not yet comply with
	the standard and are therefore not yet interoperable at
	the Advanced Simple Profile.
	They *are* compliant with Simple Profile, though, and might 
	also be called Simple + GMC and/or B frames and/or 1/4 pel.
