I've personally been involved in Joomla-powered commerce
sites with
>350k pageviews daily, as well as some internal sites
with thousands
of user accounts. Joomla can scale, and with minimal effort
can scale
to a pretty big extreme.

Theoretically speaking, you're limited to your deployment
and how you
got MySQL setup.

Again, the limitations of the infrastructure are probably
rediculously
far out there to worry about. However, you will need to make
some
modifications in order to manage load-balancing, as well as
some
modifications to the default admin template in order to
manage that
much data.
Ultimately what becomes your biggest issue is how much you
rely on the
admin interface to manage such a large pile of stuff.
Remember that
one of the strengths of Joomla is its flexibility; and
you're free to
create your own admin template - and therefore also admin
"screens"
that are specific to the scale of your site's requirements.

I've recently contributed memcache storage for both sessions
and
caching storage to the 1.5 tree, and combine that with some
simple
work to facilitate load-balanced environments, you can take
Joomla 1.5
to pretty big extremes.
I'm currently building a site based on the 1.5 framework
(not using
the CMS) for a site that gets around 40M pageviews every
week. Would
love to do a case study at a future NYPHP event if I pull it
off 
Once this is done, I'm starting up a high-traffic Joomla
group
specifically to deal with such issues, as there are a lot of
media
companies that are attracted to the attractive possibilities
of using
Joomla as their base platform - and I'd like to provide that
resource
to the community.
