Reluctantly, I have to weigh in on And's side here, after much mental
muddling while writing the phonology paper. The phonology is broken in
the area of buffer vowels.
The principal trouble is that buffering is done for the speaker's benefit
(unlike the pronunciation of "'" as [T] (theta) which is supposed to be
for the listener's benefit), but if the listener has learned an unbuffered
dialect, he will not have space in his Lojban vowel map for the speaker's
buffer, and will stuff it into one of the other slots ("i" or "y" or
whatever), causing mishearing.

I have added a note to the phonology paper saying that those who use buffers
should pronounce their "real" vowels longer, thus: [kI la: ma:] where
[I] is the buffer and [:] is the IPA vowel length diacritic.
Unfortunately, I fear that although the phonology is broken, it may be
too late to fix it. Either we have to define the buffer as a definite
though optional vowel, or we have to revise the morphology to allow
buffer-hyphen equivalence (meaning that "patfymamta" and "patfmamta"
mean the same thing -- currently the latter is a dubious le'avla).
This is scary, although it might work if it turns out that all le'avla
that are banned either fail the slinku'i test or involve nonstandard
medial consonant triples like "tfm" which is "t/f/m".
But if neither strategy can be made to work, then we just have to choke
down buffering as a known flaw in the language.
