Forgive me if I'm missing something basic.
I'd like to "embed" this into a website. Think of a staff directory, and you want to contact staff member NNN. I want a link they can click on, analogous to a mailto: link, only instead of opening their email client, it opens coccinella, with the connection options set to the person clicked on.
Is this possible? How to do this? Something like:
[A HREF="jabber://myjabberserver.mydomain.com?contact=scott.smith"]Scott Smith[/A]
where scott.smith is the jabber id of the contact?
Read XEP-0147: XMPP URI
Read XEP-0147: XMPP URI Scheme Query Components for detailed instructions. In short: <a href="xmpp:scott.smith@example.org?message">Scott Smith</a>. Note that this may or may not work depending on the platform and browser (e.g. it does not open a new message for this contact with Firefox on Mac OS X). It's not a high-priority bug/feature, but I can poke Mats to fix this issue if you want.
Another option is to use MiniChat (instructions for MiniChat).
