title: MSBUILD - block until a file exists on an ftp server?
body: <p>As part of a build process .. I would like to block the build until a file gets created (exists) remotely at an ftp location, after which I would continue the build. (Preferably with somekind of time out limit). </p>
  
  <p>Suggestions?</p>
  
  <p>Is this even possible using only the standard msbuild task and/or extensionPack/communitytask?</p>
