I'm just curious to know if you're ever actually looked at the hardware
options to see what OS they function on. I think you'd be surprised to find
that many of the more popular ones, are running on some flavor of either BSD
or Linux. On the support issue, dummynet is supported by it's developer,
Luigi Rizzo and he literally begs you to contact him directly if you locate
a bug in the subsystem, need some questions answered and even offers his
support under contract if you prefer.

"3. Support
If you have found some bug, please report it to me by email, but don't
forget to include information on which version of FreeBSD and dummynet you
are using, your rules (ipfw show; ipfw pipe show), your configuration
(bridge or router) etc.
If you have a simple question, again just email me and i generally try to
reply as soon as possible. Again, please supply details!
For more complex things (like "i have no time to learn how to use it, i just
want this work done"), or customizations and additions of new features to
dummynet/ipfw, I am available (through my department) for doing support on a
contract basis.
Email luigi at iet.unipi.it for discussing details."

As far as being "nowhere as good as you can buy", take a WatchGuard Firebox
X1000 for example, they're pretty popular because they work. People that use
them always tell me they prefer them to any *Nix based solution. By that
statement, I know they've not really looked into that unit because the
developers plainly state that it runs on a Linux hardened kernel. It
terminates vpn connections, both ipsec and pptp, rate limits, nats and
firewalls. All of the very same features you can do with Linux or FreeBSD
using the appropriate packages.
