unlimited is a marketing word but once it turns to juridical, it sucks.

some say they have to define a huge limit and that's it.

Limits are sometime hard to define :

- they must be such huge, a user (human) finaly understand it's unlimited else he will compare to competitors

- but no such huge because the 0.1% of users will try to reach it

A fair word could be the one which categorize the type of use :

- human : human has physical limit (e.g: typing word to keyboard / per time).

- bot : from 1 arduino to heavyweight hardcore clusting, virtualy no limits.
