Meteor.js and Kaltura

Hi there,
we built Meteor.js app to edit media/playlist metadata and upload large media files (1-5Gb) to Kaltura. During the development we first tried suggested client side jquery library to upload files directly to Kaltura ( but couldn’t get it worked on Meteor.js. We ended up with uploading our media files first to our server (using Meteor.js package CollectionJS) and then provide the download link to Kaltura (using its media.addFromUrl) to get the file there. Unfortunately this puts our server under a big stress when several large files are both being uploaded and downloaded at the same time. Does anybody tried Meteor.js to upload files to Kaltura directly?
Thanks for any help,
