		<description>as one of those OC swarmcast developers, I can also tell you that Swarmcast was only superficially like bittorrent; for one thing, Swarmcast worked ;) but the real innovation still unmatched was the insightfull use of the Foreward Error Correction -- this is the same method used by cellphone networks and this technology (not invented by Justin, just adapted to filesharing by him) is the &quot;free software&quot; core of the otherwise proprietary swarmcast technology (FEC is still on sourceforge somewhere).  

Another SC filetrading innovation in the use of hash-trees allowed swarmcast to be used for real-time live streaming broadcasts; this facility is still largely untapped by the media although I believe it was employed by CityTV&#039;s FashionTelevision to distribute their archive broadcasts (long long before YouTube and Google would make streaming media mainstream.

So why did bittorrent skyrocket after the death of napster but SC didn&#039;t?  My theory is two factors, not the least of which was that Justin just didn&#039;t go to the right parties, but also the SC implementation was in Java, and java for a windows desktop was not a popular opinion in those days.  Had the desktop client been in C++ or even Python like BT, it may have fared better.  As for being opensource, remember, in those days neither of the top browsers was &#039;free&#039; as in free speech, and the swarcast client was just as free as in free beer.

Oh, one other thought: we intentionally made SC difficult for bootleggers to spread illegal copies; to distribute content, you had to &lt;em&gt;own&lt;/em&gt; that content; that probably shot SC in the foot relative to BT more than all the other reasons combined.

But don&#039;t shed any tears for OC Swarmcast: upon the collapse of OC, Justin regained the ownership of his wares and founded &lt;a href=&quot;http://www.onionnetworks.com&quot; rel=&quot;nofollow&quot;&gt;onionnetworks.com&lt;/a&gt;, and they are still very much in business still profitably serving the industrial sector that OC would not consider ;)</description>

		<description>Opencola devoted a lot of resources to the development of swarmcast. Lots of developers worked on it for many months.</description>

		<description>Swarmcast was open source and not proprietary. Swarmcast was not developed in Toronto, but was purchased by Opencola, which never did anything significant with it other than sink it. I believe you are also wrong about Justin re-purchasing the IP.</description>
