I'd like to have the possibility of limiting my download speed.
Sometimes I'm downloading huge files which take a long time to download.
The download will also consume all my downstream bandwith. I'm behind a
router with two other PC's, if my brother wants to play a game online
while I'm downloading with full speed for an hour or so, that's
impossible for him because I'm using all the bandwith then. This is
quite a serious problem for me and other people sharing internet
connections. Maybe for other people as well, it could be useful to limit
download speed so that you can still browse the web while downloading.
Maybe you could put such a seek bar, like the one in Totem, in the
download manager window as an easy way to control the percentage of
download bandwith which is used. I've searched Bugzilla for this issue,
and I've found this: http://bugzilla.gnome.org/show_bug.cgi?id=117939
That feature request is one and a half year old however, so I wonder if
it still isn't possible?

I posted about this in the mailing list as well:
http://mail.gnome.org/archives/epiphany-list/2006-January/msg00108.html I
haven't received a response from the developers on that mail however, so that's
why I'm posting a feature request as well.
