So far, I'm thinking that gemination was merely an allophonic variation of non-geminated phonemes.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

They were, as I stated before, initially produced by allophonic differences dependent on the neighbouring vowel.    From Wordnik.com.  [PIE Uvulars: A revised solution of their origin] Reference

These allophonic realisations varying by dialect would have resulted in the variety of realisations in daughter languages.    From Wordnik.com.  [PIE "look-alike stems" - Evidence of something or a red herring?] Reference

As for the idea of long vowels being allophonic with short vowels, I doubt you'll find a clear explanation from others but it's something that I believe as well.    From Wordnik.com.  [The headache of the Indo-European subjunctive] Reference

On the other hand, it's of course ideal, if it is the same particle, that we see alternation between velar and uvular, since it would be proof for allophonic distribution.    From Wordnik.com.  [Confused about PIE's intensive particle *ge] Reference

However, in a language that lacks a phonemic contrast between "o" and "u", it would be natural for there to be allophonic, dialectal or idiosyncratic variation within that large vocalic space.    From Wordnik.com.  [The net doesn't have to be an intellectual wasteland for Etruscan studies] Reference

Alternately, if your normal/supershort shwa distinction is not supposed to be allophonic, I'd also be very interested in seeing an example of a language distinguishing length only in reduced vowels.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

You have to consider though that there are differences in languages: what phonetic cues are considered fundamental to a phoneme, differences in allophonic range, differences in the overall phonology, etc.    From Wordnik.com.  [To be or not to have. That is the question.] Reference

Although these are different sounds in many British English dialects, they are not only allophonic but in complementary distribution (that is, they never exchange places), hence do not need separate symbols.    From Wordnik.com.  [VERBATIM: The Language Quarterly Vol XI No 4] Reference

I also find it interesting that, after I've suggested that uvularity was a rather recent distinct feature only developping from earlier allophonic variation once Syncope began in early Late IE, Lass' comments on phonemic typology appear to be quite apt: "Remembering that these are phonemic - not phonetic - 'normalcy statements', we can be justified in suspecting that, for instance, if a language has a pharyngeal fricative or uvular stop phonetically, it is more likely than not to be better characterized as an allophone of something else than a primary allophone.".    From Wordnik.com.  [Markedness and the uvular proposal in PIE] Reference

3. In allophonic variation, a shared articulation feature ie. bilabiality is most economic.    From Wordnik.com.  [Concern trolls and the Etruscan bilabial 'f'] Reference

It's based on the fact that in a language without phonemic contrast between /u/ and /o/, there will nonetheless likely be free variation or allophonic alternation under the one vowel "u".    From Wordnik.com.  [An etymology for 'Rome'] Reference
