I will admit, our poll on spins.fedoraunity.org showed that more users
want to use BitTorrent. I still think these users just had no concept
of what Jigdo is *good* at and were left to deal with our growing pains
setting everything up. We do apologize for that. We do, however, 110%
support Jigdo in many cases:

* Testing images can easily be "upgraded" to the next release, only
downloading what has changed
* Re-Spins: The same goes for Re-Spins, an end users (and the testers)
can easily "update" their ISO, again, only having to download what has
changed
* Any Spin: Not all mirrors chose to carry the ISO images. A next-hop
or local mirror might not be available with the ISO images for direct
download. This very close mirror will be able to be used to "put
together" the ISO image and with our awesome new MirrorManager the
acquisition of this data source will be automatic.
* Bandwidth Optimization/Utilization: We are able to utilize mirrors
around the globe without requiring mirror admins to think twice about
hosting Jigdo data, they already are hosting most of the data needed to
put the image back together and have to install no additional software
(as in the case of running a torrent seed.)
* Official Releases: This "letter" was directed at requesting all
updates be archived in some form; this bullet is about official
releases. These official releases will *always* be able to be hosted
via Jigdo with *very little* additional storage requirements because
the Fedora and Everything trees that were composed against are exploded
and hosted indefinitely.
 
Jigdo support will be a fantastic addition definitely. Bandwidth is very costly in my country. So, using jigdo makes a lot of sense to me.
Have not yet done it just for proper knowhow.

Cheers,
Imtiaz
