Someone may need to correct me, but I believe the blogger still
generally copies the trackback url and pastes it into a form provided by
their software. Alternatively, you can use a little bookmarklet to
autodiscover the trackback url from a page's header.
So:
* When composing a post, the user provides, manually or by
bookmarklet, a trackback url.
* When the post is made available for public consumption, the wiki/blog
sends a request to the trackback url.
There is a standalone trackback implementation written in Perl, which
is pretty minimal and pretty functional.

Trackback spam is a problem, just like conventional comment or wiki
spam. You kill it in pretty much the same ways- with link blacklists.
