Great, thank you – this filter:

#!/usr/bin/env runhaskell

-- addRefEnvItem.hs

import Text.Pandoc.JSON
import Text.Pandoc.Walk

main :: IO ()
main = toJSONFilter addRefEnvItem

addRefEnvItem :: Maybe Format -> Block -> Block
addRefEnvItem (Just (Format "latex")) (Div ("",["references"],[]) (h@(Header 
_ _ _) : blocks)) =
  Div ("",["references"],[]) ( [h, latex "\\begin{references}"] ++ 
concatMap addItem blocks ++ [latex "\\end{references}"] )
  where latex = RawBlock (Format "latex")
addRefEnvItem _ x = x

addItem :: Block -> [Block]
addItem x = [RawBlock (Format "latex") "\\item", x]

together with this definition:

\newenvironment{references} {\list{}{%
    \leftmargin1.5em%
    \itemindent-\leftmargin%
    %\itemsep0pt%
    %\parsep0pt%
    }}
    {\endlist}

give very nice results now. I'll try this out a bit more and report back.

Anyway, my feeling is that using lists for bibliographies (at least in 
latex, not sure about html etc.) is probably the way to go for pandoc in 
general. Using lists, it wouldn't seem too difficult to make numbered 
styles (e.g.., nature.csl) work properly, too. pandoc would just have to 
move the first field in a CSL style file bibliography definition into an 
item label (`\item[firstfield]`), and adjust the list definition to the 
width of the widest label, of course. I'll try and figure out some of the 
details.

Thanks again for all suggestions so far!
