I hate to be so negative but I have to agree. I know many people (including myself) who've already written libraries similar to Meteor (derby comes to mind).
This is ridiculous. Meteor hasn't even gotten any real adoption and it has no business model. Why create a business when you can just get investment on promises alone?
Meteor works a lot like Heroku, and that's the monetization strategy.
Currently you can push your Meteor apps to their servers and host/run them for free. But eventually they're going to charge, have add-on services, etc. Just like Heroku, but because these are the guys who built Meteor, it should be better.
It will be interesting to see if anyone else tries to host Meteor apps at all, Heroku/Salesforce should be watching closely.
This gold rush is so depressingly familiar. But that's not to speak ill of Meteor-the-product, which looks pretty nifty (albeit not $9M of nifty).
