Imagine a site with a CONUS map (to start, and thinking small; we
could scale up) where you can use a bounding box to identify your
region of interest or cursor to select a particular point (map).
After that selection you see an inventory of different maps and types
of maps available, and you use a check-list to identify the ones you
want. The site prepares a separate page/Torrent stream to provide
these, and the page is lightly persistent (days before it ages out)
and indexed on a page of recent selections.
You'd have the option of getting the data via download or Torrent at
that point. Simplified data delivery.
In this case you don't gain any advantages of the peer-to-peer
distributed transfer. You only gain the advantage of another method
of server->client that may be easier to use at the client end.
We've seen, in another endeavor I work around, that if one person's
interested in a dataset, someone else is likely interested. So,
creating that dataset, especially if it's big/bulky and takes some time,
should happen as few times as possible.
We'd need a server with the space for 100 DVD's worth of data for
DRG's and another 100 for DOQQ's plus space for other types of maps,
professionaly backed-up. Also need a big pipe 'cuz non-Xastir
people will find it too.
Not today, but in a week? Or does it have to be today?
Now: Imagine the same kind of a setup as you describe but have it
auto-create the torrent files and keep them around, plus post them
on a web site. As maps get distributed from BIGSERVER over
torrrent, the bandwidth required would go down over time assuming
enough people became seeders.
I think you just said what I said. or tried to say.
Of course the reality is the server would become more popular over
time, but the torrents might keep the total bandwidth used more
under control. Less of an exponential rise anyway.
