Ok, needed a break from work, so for fun and for learning something new:

==============
\setuppapersize[A4][A4]
\defineparagraphs[TwoLang][n=2]
\setuptabulate[split=yes]
\setupalign[verytolerant,stretch]

\starttext
\showframe

\startoutputstream[one]
    \setupalign[flushleft]
    \framedtext[width=17.4em,align=verytolerant,stretch,frame=on,offset=overlay]
    {\input lorem }
    \hfill
    \par
\stopoutputstream

\startoutputstream[two]
    \setupalign[flushright]
    \hfill
    \framedtext[width=17.4em,align=verytolerant,stretch,frame=on,offset=overlay]
    {\input davis }
    \par
\stopoutputstream

\synchronizestreams[one,two]

\startoverlay
    {\raise2\strutdp\outputstreambox[one]}
    {\raise0\strutdp\outputstreambox[two]}
\stopoverlay
\startTwoLang
\input lorem
\nextTwoLang
\input davis
\stopTwoLang

\starttabulate[|p|p|]
\NC\input lorem
\NC\input davis
\NC\NR
\stoptabulate

\bTABLE[frame=off,align=yes,split=yes]
\bTR
\bTD[roffset=2mm]\input lorem\eTD
\bTD[loffset=2mm]\input davis\eTD
\eTR
\eTABLE

\startcolumns[n=2]
\input lorem
\column
\input davis
\stopcolumns

\stoptext
==============

The \raise2\strutdp etc. feels like a hack, Wolfgang knows better why it's  
needed, as as how and why the value for one stream affects the other..
