title: Has anybody compared WCF and ZeroC ICE?
body: <p>ZeroC's ICE (www.zeroc.com) looks interesting and I am interested in looking at it and comparing it to our existing software that uses WCF. In particular, our WCF app uses server callbacks (via HTTP).</p>
  
  <p>Anybody who's compared them? How did it go? I'm particularly interested in the performance aspect, since interoperability isn't much of a concern for us right now. Thanks!</p>
