During skipjack public beta ftp install (linux expert dd) things can appear to be hung if the ftp server is slow (like it is when Red Hat just announces the beta :)) Displaying the xfer rate (bytes/s) and the bytes xfered (xfered/total) would give the user feedback as to the status of ftp and http xfers in progress. This would be a textual feedback element and not releated to the package install or over all install progress bars. For consistancy the xfer rate and the xfered bytes should be visbible both during text installs and gui installs. I don't see this making sense for NFS however for both ftp and http installs it would be a good thing.
We are currently in string and screen freeze, but will look into this for a future release.
