Comment (by tscrim):
Well, maybe this isn't a (complete) solution (although it could be my
current implementation):
{{{
sage: Rings().Differential()
Category of additive inverse differential semirings
sage: Rings().Division().Differential()
Category of division no zero divisors additive inverse differential
semirings
}}}
