<p>Wow, folks who really don't keep up on the literature.</p>
<p>bittorent is a PROTOCOL - it's not an archive, it's not a file
system, it's a PROTOCOL - it does not store or index things, it's
used to move them</p>

Pretty soon, I'd think minutes, so long as your BT program is
running so it can serve it.

Never. Search engines don't index BT. If you want something to
be in search engines, you have to put it on the web because that's
what they search.

Forever. It's up to each user whether and when to run a BT
program.

<br>
Until it's deleted from all the hosts that have downloaded it, but
if none are running BT program, it won't be accessible.

That would be a web server with a budget.

That only works until they lose interest.
