Great, thanks!

Nice.

Well, more or less you're right.  I did remembering of websites before
and used something like 'emacsclient -e (my-custom-function "url")', but
then I have to hassle with shell quoting and write a new custom function
for each task.  Therefore I like this standard interface better.

And, of course, since you can add a handler for org-protocol:// in a
browser, I guess sites like orgmode.org, Worg and emacswiki will
eventually start using links like that.

BTW: How do I set "emacsclient -c" as handler for the org-protocol?

Bye,
Tassilo
