There are lots of upsides: it’s easy to get involved by sharing a smallish chunk of the set, the relatively small tracker file can be separately copied around to ensure there’s no single point of attack, perhaps even via git or something similar to ensure it’s not tampered with (and made trivially available via github), and it’s pretty fire-and-forget (just leave it running on a routable server).

That’s something that we may want anyway, just to ensure the thing can always be seeded (at least until the feds come knocking, but hopefully by then there are many redundant copies of the data sitting around the world).

I was thinking about using the torrent protocol last night and i think 
there are two issues that would prevent this:

- we'd have to generate check-sums for every dataset that is stored, 
then generate URI's for each of them.  I am pretty confident the data 
here is not bt friendly...which leads to my second point

- the academic/prof consumers of this data are probably not going to use 
bt to download these files for research.  unfortunately ftp and http are 
probably used very frequently in these arena's.

having said this - i def feel that bt would be a *much* better method to 
distribute and share the cost of hosting data...but i'm not sure if they 
are ready for this or not :)
