Use \url with pipe argument delimiter - in hyperref?

Question

Basically, I have a bibtex field like this, where bibtex concatenation with # is used with a bibtex string variable:

@String {mylink = "http://tex.stackexchange.com"}
...
note = "At link " # mylink,

Now, I'd like to wrap that in a \url, so I tried:

note = "At link \url{" # mylink # "}",

... and when processing with biblatex+biber, it seems that the presence of braces makes the parameter mylink to not be replaced.

Reading through texdoc url, I learned that \url there actually has another call form \url|...| where instead of braces, I could use pipes as "argument delimiters" - and indeed this is expanded properly by biblatex+biber:

note = "At link \url|" # mylink # "|",

... but unfortunately, hyperref's \url command does not support this syntax with the pipes - and url's \url typesets only plain text (not clickable links in PDF).

So, is there any way to have \url|...| be "understood" as url's \url (that is the pipes represent argument delimiters) - but executed as hyperref's \url? (with clickable links and all)?

Here is a MWE that shows just the \url aspect (without the bibliography):

\documentclass{article}
\usepackage[showframe]{geometry}
% \PassOptionsToPackage{hyphens}{url}
\usepackage[hyphens]{url}
\let\origurl\url % same as \HyOrg@url (from hyperref)
\usepackage[breaklinks]{hyperref}
\hyphenation{some-folder-with-a-very-long-name}% doesn't work
% \hyphenation{http://testing.org/firstlevelsubdirectory/some-folder-with-a-very-long-name/2008010817502377777777/}% '! Not a letter.' for the ':'

% cannot use \hyphenation to break urls; so make it break link at each letter!

Output:

I'd like to simply write \url|...|, and have the link output/typeset as on the first line in this MWE (while for now, I have to write \origurl|...|, and it outputs as on the second line - without a link area).
