title: Open Source & Cross Platform Multiplayer/Networking Libraries?
body: <p>While <a href="http://www.jenkinssoftware.com/" rel="nofollow noreferrer">raknet</a> seems fairly interesting and really appealing from a feature-point of view, its <a href="http://creativecommons.org/licenses/by-nc/2.5/" rel="nofollow noreferrer">licensing terms</a> seem to be possibly troublesome for GPL'ed projects that may be leveraged commercially, something which is explicitly forbidden by the terms of the creative commons license. </p>
  
  <p>While there's also <a href="http:///www.opentnl.org" rel="nofollow noreferrer">opentnl</a>, it doesn't seem to be as actively maintained anymore nowadays, in fact downloading the latest stable tarball even fails during compilation because it doesn't seem to support gcc >= 3.0 (?)</p>
  
  <p>Of course, there's still also <a href="http://enet.bespin.org/" rel="nofollow noreferrer">enet</a>, but this one cannot be really compared to the abstract features that are supported by raknet/opentnl.</p>
  
  <p>So, apart from any non-trivial dependencies such as ACE, Boost or Poco, are there any viable alternatives for embedding a fairly compact, well-maintained UDP-networking library?</p>
  
  <p>Thanks</p>
