Yup. The only way to host fanfiction without the author's explicit permission is 50 years after the author's death.
And unfortunately, by that time, it would probably be too late. Are you aware of the whole "orphaned works" debate regarding copyright? There's also the fact that some countries don't have a "public domain" clause. I'll respect the authors as far as I reasonably can, and I'll be adding some disclaimers and policy statements shortly, but I'm not just going to sit around and let amazing stuff fall off the web. It took me MONTHS to figure out how to squeeze the last few chapters of Trial by Tenderness out of the wayback machine.
I would put my policy here (which would probably assuage most of your worries) but as I'm about to explain, I'm stuck using a text-mode browser and it limits the number of lines I can put in a textarea.
The first two steps mimic the results from an extremely persistant automated archive, the third mimics any reasonable archive site including the abandonware sites that have survived since the beginning. That's my policy and I've already compromised as far as I'm willing to. Were I a dictator, using robots.txt to prevent archival would be illegal. (things like phpBB would be required by law to have a "retrieve content diff since..." link to compensate for how unfeasible it is to spider a forum)
Among the many reasons why I"m so fanatical in my "what was lost can never be recovered" views is that my favorite piece of music is Tomaso Albinoni's Adagio in G Minor. To quote Wikipedia,
Much of Albinoni's work was lost in World War II with the destruction of the Dresden State Library, thus little is known of his life and music after the mid 1720s. The Albinoni Adagio in G Minor is a 1945 reconstruction by Remo Giazotto of a fragment from a slow movement of a trio sonata he discovered among the ruins of the State Library.
To elaborate on what I mentioned a little earlier, Starting shortly after I posted, I lost the ability to read FukuFics on my computer (timeouts) and I'm completely stumped because it's not specific to any one browser, and it works on any other computer (my brother's, my mother's, the router), but it means that I have to SSH into my router and use Lynx (a text-mode browser. no mouse, no CSS, no graphics) to read replies. (Links2 supports mouse, but for some reason, I can't log into FukuFics using it)
Here's a screenshot to illustrate my point: (as you can see, I'm using a notepad-like program to compose my reply [url=http://img523.imageshack.us/my.php?image=snapshot1sa3.png

*shrugs* I think Celeste Byrd's fics would qualify... though the only one I really remember was Project NK Ranma.
Inelligible unless Studio Asynjor goes down. However, I do keep an HTTrack-mirrored copy of Studio Asynjor on my hard drive in case such a thing happens. (In the portion of the drive that gets mirrored to two other drives nightly)
I'll clean this post up as soon as I have access to a browser which doesn't limit the number of newlines in a textarea.
