Actually, the Texas law in question reads as follows:
SECTION 6. Sections 31.14(a), (b), and (d), Penal Code, are
amended to read as follows:
(a) A person commits an offense if the person intentionally
or knowingly manufactures, assembles, imports into the state,
exports out of the state, distributes, advertises, sells, or
leases, or offers for sale or lease:
(1) a communication device with an intent to:
(A) aid in the commission of an offense under
Section 31.12 or 31.13; or
(B) conceal from a communication service
provider, or from any lawful authority, the existence or place of
origin or destination of any communication;
(2) an unauthorized access device; or
(3) plans or instructions for assembling or
manufacturing a communication device or unauthorized access
device, with the knowledge that another person intends to use the
plans or instructions for an unlawful purpose
_______________________________________________
Section 6 (a) (1) (B) does deal with the legality of equipment or software that is used to "conceal from a communication service provider, or from any lawful authority, the existence or place of origin or destination of any communication." However, Section 6 (a) shows that this is only a question of legality in relation to those who would sell, lease, or import such equipment into the State AND it must be done intentionally or knowingly. Furthermore, it appears in the overall context of the bill, that this is only in relation to action taken in selling/leasing/importing this equipment "with the knowledge that another person intends to use the plans or instructions for an unlawful purpose."
That being the case, I would suggest that this bill will not be used to attack firewall owners/users or PayPal users at all. Instead it will be used to prosecute those who are trying to rip off ISPs and such. Even so, I will agree that the bill could have been worded more explicitly to have excluded private, legal usage of firewalls and the like.
