"SIGINT tradecraft…is very hands-on (li terally!)"

There's now precedent to suggest that providing FISA-ordered data in a
deliberately inconvenient format can be considered contempt of court.
The case establishing it? Lavabit printing out their server TLS keys in
small font. That's not even such a big deal, because OCR could still be
used trivially if the opponents weren't tech-illiterate. Depending on
the type of key, you could probably even detect OCR errors quickly by
checking for primality or group-compatibility for the key subunits.

So that's even less technically troublesome than what you're suggesting,
and it was contempt. I don't think the telecoms would get away with it,
even if they did care a damn about customers.

He meant, "not on paper", because if it were on paper, that would be very difficult to actually USE.  My idea was to put the information onto pdf files, where if you view the pdf file, it would look like lines of "captcha"-type data:  Weird, warped characters, in various odd colors, overlapping lines, etc.   CAPTCHA - Wikipedia, the free encyclopedia    Specifically designed to NOT be computer-identifiable.  The essence of the presentation of the data would be that it wouldn't be readable by 'computer' at all; it would have to be decoded by human intervention...even though it was in "electronically-readable form"!!
