[IETF-IDRM] Re: IDRM research group closed

[chris mollis]

Since the ISMA DRM spec is unavailable, we've implemented a simple 'hook's
implementation on top of the 1.0 spec.. there are some ISMA 1.0 issues we've
had to deal with, however. For example, the length of the URL field that
holds the OD track isn't long enough hold a full DOI and we can only use
symmetric keys in CFB mode because of packetization issues.. things like
this... We wrote up as many issues as we could and included them with the
release...

Is this connected at all with the ISMA MPEG-4 DRM solutions ?
