Comparison with other P2P software
Review of online TV offerings
Joost is made by the team which was also behind Kazaa and Skype
For an analysis of Joost both the technology and the history of this team are important.
Kazaa and Skype are both for-profit initiatives that defined the state-of-the-art of P2P at the time. However, Kazaa was bundled with spyware and also took the referal credit for sales on Amazon.com. Skype was sold for $2.6 billion in up-front cash and eBay stock.
The business model behind Joost is likely another takeover. Joost is inserting advertisements between programs to obtain reveneus using proprietairy software. At the technology level; Joost still requires central servers to offer Video on Demand and only supports a single bitrate. The P2P protocol is fixed at 720Kbps H264 encoding and is architecturaly constraint. It is expected that the Joost architecture will not scale to HDTV-like bitrates. The interface of Joost is very simple and elegant, their key selling point.
What Babelgum lacks right now is a compelling differentiator â it needs to offer better content, better features or better technology than Joost and any other upstarts if it wants to win, from a review by Jackson West

a few dedicated seeders. which are in the screenshot below:
When resolving the above seeders using DNS we find that a few dedicated seeders are used
from the Azuereus people themselves.
We conclude that a few dedicated seeder which send chuncks in the first seconds really ease the problems of P2P Video on Demand.
Earlier "Democyracy player" RSS Video Aggregator using BitTorrent for transport (likely also http if so specified in the RSS). Very nice GUI, based around "Channels", which are RSS feeds. Channels are divided into different types of content, as well as "most popular", "new" etc. Video player is embedded, making the user experience good. Lot of suggestions for stuff to watch, quite a lot of high resolution content. Also has search capabilities. Will also suggest "if you like this channel, you might like ...". Memory consumption seems improved since "Democracy player". Knows about which episodes you've watched, auto-downloads and deletes. Remembers play positions if you want to resume watching an episode. Annoyance: "Auto-download" downloads newest first, while it should have been the oldest first (or at least configurable) pr channel.
