It may not be of use to you if you don't have a website that you want to 'embed' a slideshow into, or a blog that you want to 'embed' a slideshow into. But there isn't a way to supply a link to this because it is not a page on a site, it is 'embedabble code' that will produce a slideshow on the page that it is embedded into. I think you are misunderstanding the technology.
If you want a 'link' that you can show people or send in an email to people so when they click on it, they are taken to a slideshow, Zenfolio has offered that feature for sometime now, and you can access that link by clicking on 'edit' in the link box in edit view. Then you will have a link you can paste into an email, and when someone clicks the link it will take them to a slideshow of the gallery you were getting the link from.
But again, very different things here, for very different purposes. The one you are saying you want, is the one Zen has had for a while, and works very nicely! :)
Hope that helps clear up the confusion.
