The ACTA treaty confers powers with dangerously broad and ambiguous language - an example is language to ban:
a device or product, including computer programs, or provision of a service that... has only a limited commercially significant purpose other than circumventing an effective technological measure.
So legitimate purposes that are significant, but can be made out not to be commercially significant, won't protect you. Education and research purposes, and fair use gone, at one stroke!
The international coordination is all about the interests of "intellectual property" owners (mostly distributors, in the content industries), and not about consumers or the broader creative economy. The only stakeholders explicitly mentioned are "rights holders" - if we're lucky, the rest of the world may sneak in as "other relevant
stakeholders" - but don't hold your breath - it hasn't happened yet, and isn't happening in the shady negotiations for the Trans-Pacific Partnership Agreement. And the only measurement or analysis to be done is about how well they tackle the nut of infringement, with no examination of the sledgehammer of social and economic costs of the enforcement regime ACTA requires.
Then there are the optional extras such as:
A Party may exclude from the application of this Section small quantities of goods of a non-commercial nature contained in travellers’ personal luggage. [a Good Thing]
A Party may provide for the remedies described in this Article to be carried out at the infringer’s expense. [not necessarily A Good Thing]
A good government would implement the protections ACTA says they MAY do, and omit some of the more onerous and opressive powers the lobbyists got into ACTA as optional extras.
Our governments, on the other hand, will use draft legislation written by the same content industry lobbyists who wrote the original ACTA policy shopping list, and will try to omit every inconvenient consumer protection measure some ACTA negotiaters insisted on, and include each of the overreaching powers the negotiators reduced from MUST to MAY in ACTA.
Or we can just stop worrying and hope that the law-faries will bring us cuddly, fair and reasonable legislation that servers the public interest, instead.
