[cooperation-wg] What governments don't get (feedback on data retention)

Hi all!  After applauding Malcom yesterday, I've recognized a parallel
between VAT and wiretapping:  They both don't work well with layers.

Traditionally, telephony is conceived as the service of a single operator.
Suppose that the telecom splits among various intermediaries.  Actually,
several large industries define such kind of split internally, for
administrative purposes.  However, if the split is real each provider of a
service layer has to pay VAT, while departments don't.  By a similar logic,
if cryptography is deployed at some layers, then wiretapping has to be
coordinated with those layers as well --possibly not the network provider or
cable operator roles that the directive targets.

Can someone suggest a solution that would solve both issues :-)
