| I haven't personally used the Hawkings HBB1, so I can't speak to its
quality. I only remember reading a review on it somewhere on the
Internet.
The biggest issue when it comes to an asymmetrical link like Cable/DSL
is mostly your upstream speeds, not the downstream. Three things are
required to resolve the upstream problem at the edge. Prioritization
(making sure that critical packets get priority over non-critical
packets), Shaping (making sure that you are not trying to force more
information into the link then it can handle e.g. softball into a garden
hose), and LFI (making sure you break packets down so that they are not
delayed due to packet with larger sizes).
These are all things you can do in a cisco 830/870 series router,
however be mindful that you can QoS everything until you are blue in the
face and you can still run into issues once it leaves the confines of
your network. The above features will improve your overall experience,
but you are still at the mercy of the Internet when it comes to delay
sensitive traffic.
Matt

| Since the ASA5505 is now orderable, I doubt we will ever see a PIX501/506
supporting the 7.x code
