	Indirectly, yes.  It will also indirectly interpret any Sun
	file servers (I've never seen one, just saw it mentioned here
	before), or anybody that registers themselves on the network
	as an AFP server, and follows the AFP protocol.

	There actually would be a very large difference between the two
	FST's (AppleShare and HFS), because the FST *is* the low level
	interface (well, actually the driver is...), and has to interpret
	all the raw data, and make sense of it.

	It really is ProDOS, but with added features.  The ProDOS FST
	adds the "Extended" file storage type, and automatically sparses
	files on writing.  Just like the IIGS is an Apple II, but a IIe 
	can't run GS Specific programs.
