Etherium: hype, maybe not a scam. I personally don't see why they need $35m.
Emunie is interesting in some ways.
The emonie developer, however mercurial and paranoid he may be, has recognized that mining in bitcoin is mostly superfluous. The most valuable work in the network is transaction clearing and validation, and it is this work that should be subsidized with new coins (no more need for transaction fees). Mining in bitcoin is just a way to pick who gets to create the next block by running a race. Picking who gets to create the next block can be done in some random way, which is more egalitarian.
Possible cons:
Proprietary, whitepaper and source code withheld. Can't be properly vetted by the community.
Statement to the effect that emunie "will comply with the law" or attempt to disallow illegal activity. What this means in practice is hidden back-doors for law enforcement/nsa/etc, blacklisted accounts, and a host of other nightmares (the source is withheld, ouch).
The coins can't appreciate in value (any increase in value causes new coins to to flood into the network). Appreciation is incentive for early adopters, since early on the coins will have little use. The fact that users will be granted a stream of coins for just connecting may be alluring at first, but disappointment and abandonment may follow (the first paycheck from that first minimum wage job is nice, then you realize just how long it will take for you to actually earn anything substantial).
Might be overrun by botnets or farms, which could sweep up most of the new coins generated. Worse, a botnet could send transactions between its nodes to stimulate what appears to be demand. Most cryptocoins can be abused by botnets, but emunie's network might be stimulated to respond with a coin flood (I'm a bit unsure on this point, maybe not possible/feasible?).
Conclusion:
Some of Emunie's ideas are good ones, but emunie itself is not a candidate for adoption. It would be nice to see a group of open source developers adapt those ideas into a new altcoin.
