It is already a crime to passively posses certain combinations of bits (i.e. that directly or indirectly [zip, truecrypt] represent a child porn image).
It has been made illegal to possess the implementation of a mathematical function (i.e. Kerberos being a "Auxiliary Military Equipment"). It will be pretty trivial for the government to make it ilegal to download, posses or install a program (e.g that interacts in some way with the Bitcoin network).
