[Matroska-devel] Free DRM Superdistribution

Conceptually the format can support it but in reality there is no such support.
You could make your own tools (or modify existing ones) to create DRM'ed content but I don't believe that any of the existing splitters/players et. al. that support Matroska playback would be able to handle the file which is what Moritz Bunkus' concern was when I asked for it.
So in short, you either have to get Matroska developer buy in, or you have to write all the pieces yourself (for all desired platforms) and support them yourself.
Alternatively you have to use VFW compatibility mode with your own codec that tries to figure it out from the data it is given but this is neither elegant nor codec independent and isn't what you are looking for.

I asked back in 2005 and was told that the format could support DRM.

You can search for 'Andrew Abbass' on google and it should be the
first link that pops up.

I'm looking for support within the open source community to provide an
alternative model for independent artists looking to publish their
work online. So far, the matroska system seems to have the most
potential for providing such a cross-platform solution without tying
the system to a particular codec.

The key idea behind this push is that the databasing company will no
profit directly from the system. Instead it serves as a non-profit

I hope to hear back from the developers soon. I've been contacting the
EFF and a number of other agencies in the hopes that I might spark
some interest.

I think it's time the open source community stepped up to the plate
and offered a superdistribution model that didn't serve just to
benefit the private corporate model.

Thanks for your offer of support. I hope to be able to provide you
with more information as it becomes available.
