Actually, that's not a good comparison.

But basically "software" v. "hardware" means:
  A.  The main CPU is taxied/tasked with extra overhead
  B.  It requires an OS-specific driver of additional complexity

Even looking past A, B is the killer.  And most OEMs just "buy" someone
else's implementation anyway, and then do a few customizations.  One of
these years OEMs will learn to work together, help fund a "general"
library which they all use, then write a small little driver that just
interfaces to it.

Damn, I guess we already have something of the sort under Linux, eh? 
Too bad OEMs don't give a flying fuck.  You'd figure they'd wish Linux
caught on for pure development sanity sake.

without a written agreement.  But if you want to "transfer" it,
they say it's not "like a book" but "licensed" under agreement.
