Um, maybe a Ubuntu users forum isn't always the best indicator of what
Debian package management can do.

No need to re-invent the wheel, both wget and curl can download from a
url, and dpkg will install. eg:-
$ wget $url;su -c "dpkg -i $DownloadedPackage"

Note that's just pseudo commands.
You could script it properly as a one liner in .bash_aliases (%1 to get
$url and sed that for $DownloadedPackage) or a module in .bashrc.
I'd be *very* wary of installing packages from a url. Better to use a
signed, trusted repostitory - or check out the source and make a package
from that.

You could maybe also create a little script that did "su -c "dpkg -i %1"
and associate the script with the .deb extension in Iceweasel/whatever
