The issues with GIF and arithmetic coding variants of JPEG relate to
patents. In the case of GIF, the patent was not owned by the people who
specified the format. Patents are a serious problem for open source
because independent development doesn't avoid the patent, not does lack
of knowledge of the patented product.
As already hinted, you would probably need to use trademark law and that
might well involve running certification tests which developers would
have to pay for, in order to maintain the integrity of the trademark.
The other way of protecting protocols is by non-disclosure agreements,
but those are completely at variance with the spirit of open source.
(One of the reasons for consistent implementation of the Huffman variant
of JPEG is that nearly everyone uses the open source libjpeg library
that was created by the specifiers.)
Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
