keywords as a core extenstion

[Nigel Tao <nigel tao myrealbox com>]

Keywords in a nutshell: I type "wp Epiphany" and my browser goes to
http://en.wikipedia.org/wiki/Epiphany

The feature request was raised recently (and doubtless previously):
http://mail.gnome.org/archives/epiphany-list/2005-November/msg00021.html

which pointed to a bug report with patch:
http://bugzilla.gnome.org/show_bug.cgi?id=118618


First of all - what is the "right way to do it"?  In particular, which
signal should be caught to do the address re-write?  The above patch
hooks into the "resolve-address" signal.  Alternatively, the
sample-python-location tutorial extension (which listens to the
"ge-location" signal) seems really easy to tweak into the proof of
concept one-pager at the bottom of this e-mail.

Second - what plans do the Epiphany devs have (if any) of "blessing"
this feature (as part of epiphany-extensions, presumably)?  Because I am
hoping to provide it through the deskbar-applet, even if the preferred
browser is Epiphany rather than Firefox (boo, hiss :-).  So, what would
make this part of Epiphany 1.10?  How can I help (I'd be willing to do
some coding/writing)?  Or will I otherwise have to install an Epiphany
extension as part of deskbar-applet, and mess with bookmark storage
(which is itself another discussion)?

thanks,
Nigel.
