1sp is the smallest measurement that TeX can use. Internally, I think,
all measurements are done in terms of sp's. (another way of looking
at it is that all measurements are done in pts with a fixed point
representation using 16 bits of fraction).
1sp *is* useful sometimes when you need something to be different from
0pt but not visibly so! i.e. giving a font a slant of 1sp makes
LaTeX think that it is an italic font when using \em - this can
sometimes be useful.
