As far as I can understand, there are severe technical difficulties that 
prevent this from being implemented now. As an example, see 
bugs/progerror-lyrics-staff.ly. \lyricsto is simply not intended to be used 
sequentially (IIRC, Han-Wen considered that bug a far-future thing, it would 
requiring something like a rewrite of \lyricsto). 

OTOH, it's interesting to discuss how lilypond's behaviour ideally _should_ 
be.

I have another suggestion (which probably is just as hard to implement as 
yours): Add some kind of invisible special rehearsal marks among the notes. 
They would mark certain spots in the music, where verses can start. I.e.:

<<
{ c d e f | c d e f | a \lyricmark "verse1" a a a | a a a a }
\addlyrics { bla \gotomark "verse1" foo bar foo bar }
>>
-->
{ bla \repeat "volta" 7 \skip 4 foo bar foo bar }


BTW, this thing might be a nice feature for notes as well, if it is possible.. 
like
<<
\context Staff="solo" { c4^"solo" d e f | g^"tutti" \notemark "tutti1" a g f }
\context Staff="orch" { \skiptomark "tutti1" e4 f g a }
>>

(of course mmrest-of-length can be used to solve the same problem, however 
this might sometimes be a more convenient syntax)
