How can we speed up rpm downloads?

Is there any current work on yum-presto, deltarpm or some other method of
getting the downloads for updates to be smaller and quicker?  Can you
compress rpm's to make the the downloads faster?

Currently with yum presto there is only one site that I have found that has
the deltarpms.

Currently now on a fresh install of F9 && update

Large rpm's are very time consuming to update and/or install.

Guess I answered my own question earlier, I ran gzip on openopfice.org-core
and it went from 84MB to 83MB.

Fairly loaded question, don't say get a better ISP, I have a very fast
connection at home, and this d/l view was taken at work with an extremely
fat pipe.  The problem is size of rpm's being downloaded.

Debian seems to d/l much faster, not exact version but you can get some idea
size wise.

http://packages.debian.org/etch/openoffice.org-core

wget
http://security.debian.org/debian-security/pool/updates/main/o/openoffice.org/openoffice.org-core_2.0.4.dfsg.2-7etch5_amd64.deb

There package is 34MB.

This is an example of one of the larger apps out there I realize that, I
just grabbed the last one to use as an example.  At 34MB it still takes
time, but .deb is 50MB cheaper that the .rpm.

Is deltarpm's the solution?  Has anyone talked to all the fedora mirrors to
have a deltarpm repository?
