What would be great is each time you copy that data, it mutated a bit... and if the mutation was positive, you could copy it again.

I see what you did there, with that...

Just imagine the sexually transmitted advertisements. Get a strange rash for a few days that has an ad for condoms printed on it.

Having multiple partners is not a backup method!

Redundant array of inexpensive di?ks =)

Insert Obligatory 'Diamond Age' reference here.

EDIT: Yes well for those who haven't read the book the reference is to the sexual transmission of data. Implied (but not confirmed) by nano-tech, however no implementation details were provided (as I recall), so encoded DNA might have been a possibility as a medium. Just sayin'.. /shrugs/
