More precisely, here is the font family setup of ConTeXt
	
	\fam
	0     math roman (with uppercase greek)
         1     math italic
         2     math symbols
         3     math extension
         4     italic
         5     slanted
         6     bold
         7     --
         8     bold slanted
         9     bold italic
         10    smallcaps
         11    typeface (sans serif or typewriter or ..., text font)
         12    math symbols a (ams)
         13    math symbols b (ams)
         14    math symbols c (mathtime script)
         15    math symbols d (mathtime greek upright)

Only family 7 is really empty, and only 14 and 15 can easily be
redefined (\newfamily always returns 15)

256 families of fonts with 65536 possible characters each, just like
in Aleph.

Not sure that would make sense. Font switches in math mode are in fact
different from ones in ordinary text. {\sl A} and {\bs A} may well have
completely a different meaning.
