WHOA! Step back for a minute.
There are two big differences between image and audio: First, a lot
more image formats have proliferated and created entrenched user bases.
Second, there is nothing nearly as ubiquitous as the telephony standard
for audio.
The closest candidate: G3FAX. But I'm not seriously proposing it as an
image/basic format, either -- there are lots of problems with it. All
I'm saying is that the disagreement between Bill & Marshall is the tip
of the iceberg. I predict that image/basic is a minefield, and I
recommend that we tiptoe around it. -- Nathaniel
