For testing:
\def\dodouseURL[#1][#2][#3][#4]% to be redone: not too tricky redefs ad reuse
{\iffirstargument
\iffourthargument
\setgvalue{\v!file:::#1}{\doexternaldocument[#2][#3][#4]}%
\else\ifthirdargument
\setgvalue{\v!file:::#1}{\doexternalurl[#2][#3][#1]}%
\else\ifsecondargument
\setgvalue{\v!file:::#1}{\doexternalurl[#2][][#1]}%
\fi\fi\fi
\fi}
\def\doexternalurl[#1][#2][#3]%
{\bgroup
\doifsomething\@@urstyle{\let\@@iastyle\@@urstyle\let\@@urstyle\empty}%
\doifsomething\@@urcolor{\let\@@iacolor\@@urcolor\let\@@urcolor\empty}%
\doexternaldocument{#1}{#2}{\url[#3]}%
\egroup}
(nasty bug to solve in the right way)
\setupcolors [state=start]
\setupinteraction[state=start]
\setupurl [color=blue]
\useURL[one][http://www.google.com/]
\starttext xxxx \from[one] xxxx \url[one] \stoptext
