<p>I'm using Hudson and Maven 2 for my automated build/CI.  I can build fine with maven from the command line, but when I run the same goal with Hudson, the build fails complaining of missing artifacts.  I'm running Hudson as a windows XP service.</p>

Besides another commercial product, like
Wowza Media Server
, you could go with a CDN (Content Delivery Network), like
Limelight Networks
or
Voxel.net
.  You might even be able to find a local hosting provider that would serve up live Flash video for you.
(Live Flash video in a non-trivial thing to do, so the options are a bit limited.)
