I still wonder if the IETF welcomes it, anyway.

Don't care that much about names, but it should be 'Lhomme' instead of
'Lhome'.

How does one play a Matroska file with Firefox? It supports WebM which
is a subset of Matroska, but I am unable to play a Matroska file that
contains an h.264 encoded video, which is supported by Firefox as well.

The specifications would probably benefit from any review process.

What would 'take control' actually mean? Assuming Matroska v4 gets
standardized, could a potential Matroska v5 be created without the IETF?

Speaking of subsets. The WebM Project takes Matroska and transforms it
into something new (a subset), but Matroska stays what it is.

Why doesn't PREFORMA use a subset of Matroska, which would be
standardized on its own?

p.s. I might not provide further input, today or tomorrow, depending on
whenever I'm at my computer or not.
