Yes.  A particular pronunciation scheme may have phonemes, Plan B
itself doesn't.  It is a bit stream language.  One could
*metaphorically* say that the bits are the "phonemes", but only
metaphorically so.  Bits, after all, don't live in the human
phonetic space.

Yes, that's the rule - and the quartet boundaries don't even really
matter with regard to this rule: if the first quartet is '1111',
look at the second; if that is '1111' too, look at the third; etc.
The rule is: If n is the position number of the first '0' bit
in the morpheme (starting with position number 1), the morpheme
is 4n bits long:

0...     ->  4 bits
10...    ->  8 bits
110...   -> 12 bits
1110...  -> 16 bits
11110... -> 20 bits

and so on.

Yes.  The term 'alphabet' is used in formal language theory for any
finite set of elements from which "words" (i.e., strings or sequences)
are built, no matter what those elements represent, if they represent
anything at all.  The phoneme inventory of a spoken language is an
"alphabet" in this sense, as are, for instance, the 20 amino acids
proteins are built of.

Yes, it is indeed a pity.  He could have made so much out of it,
and makes so little.  Your schemes are superior in that they derive
the pronunciation systematically from the actual bit pattern.

I think I will also revise the FrathWiki page on X-1 ...

Amen.
