Sure, you would like it to be that way.  In reality though - they now
have to meet the CableLabs requirements to preserve the DRM from
end-to-end, which means that they will be compelled to add support for
Windows DRM.

Just to be clear, we're not talking about a simple "copy flag"  that
we could just choose to ignore.  We're talking about strong encryption
and advanced key management integrated with Window's DRM and key
protection mechanisms.

Making any of these things work is going to be a *huge* undertaking
that the vendors are going to be contractually compelled to not only
be of no assistance, but to actually prevent it from being done by
others (the OCUR contract requires them to fix security holes that
result in the decryption of content or recovery of keying materials).
