Couldn't the browser remember your home instance as an autocomplete "url" value[0]? So you would click the "Add this person as a friend on my home instance" button on the third party page, and it would bring up a little text box which you could fill and submit with a couple of clicks, then it would redirect you to your instance with an agreed URL parameter, so that your instance would ask whether you really wanted to add them. Assuming your instance remembers who you are with a cookie (and the third party instance can remember your home instance too), the process could be minimally onerous.
