as far as torrenting goes. it seems you need to get yr torrent program to turn it into a public torrent .
so you would just copy the blk0001.dat -> EXCLbootstrap.dat (or whatever) then turn it into a torrent.
i've never done it
but i guess you'd have to add info etc.
otherwise if you have a server, you could copy the blk0001.dat -> EXCLbootstrap.dat (possibly adding a date or summat) onto a public server folder, then anyone can just look at the folder and ftp it or whatever.
alternatively use dropbox,
copy the .dat to yr local dropbox folder tehn dropbox can move the file to a public dropbox folder.
i run dropbox on the digital ocean vps to move files around, it's pretty handy.
.the next step would be to automate it, so it updates the bootstrap every couple of days or whatever.
then anyone could go to the public folders and download the latest or whatever is there.

taking those seeds out have sped up syncing time considerably. it's currently loading a block between 2 - 6 seconds or so. much quicker than before where i was honestly ready to leave it and worry about getting my coins later.
but a bootstrap would be quicker for sure
