Isn't this easily circumvented? (Score 2)

Suppose the author of one of the Napster interface programs (say Napigator) decided for privacy's sake to build in a function which took the names of all of your shared mp3s and using a one to one conversion/encrytion (hell he/she could even use pig latin) reported all of your mp3 files that way to the napster servers.

Then suppose the author incorporated the reverse conversion into the search function of the same program. The Napster filter wouldn't suspect a thing and the whole process would be transparent to the end users.

Of course napster could then be ordered to filter this out - then the author picks another conversion - then filter - could go on for a while. :)
