I see that this has been asked here before, but nothing since Meteor.http
has been available. I\'m still grasping the concepts of Meteor and file uploads are totall
well been playing a bit with meteor. Made a collectionFS a mix of meteor and gridFS (could be compatible). Test it here: http://collectionfs.meteor.com/ It support quit large files, multiple files, users etc. I've tested a 50Mb seems ok, if connection is lost or browser dies the user can resume upload. It should even be possible to have multiple users upload to exact same file - haven't quit found a usecase for it, but it's possible. Accounts, publishing etc. is as with collections - the test is in autopublish mode, though only meta data is avaliable - chunks of data is served in background via blobs.
I'll try getting it on github,
