Ouch. Meteor's data syncing is great, but it's not a mandatory part of real time.

That said, from their web site:

> Feathers is completely open source and is community supported, whereas Meteor, although open source, is venture backed and has raised $31.2 million to date.

A license is either Open Source (it meets the OSD) or is not. There is no 'completely open source'. I think Meteor's overvalued too, but you're not 'more' OSS than Meteor is.
