Will you make a legal opinion available to investors? I think that ethereum's main first usage will be things that are hard or illegal to do with existing systems (Silk Road), and that when Senator Schumer demands that something be done about it, the website will be seized. Bitcoin got around this problem by functioning only as a currency and externalizing the Silk Road to the Tor network. I don't see how ethereum can compete with bitcoin if it is driven underground.
For what it's worth, I really hope this succeeds. Self-regulating markets are far superior to what we currently have. I am just not convinced this has a reasonable chance of success yet.
We will have a legally vetted prospectus available on the first day of the fundraiser that will contain our terms and conditions as well as the risks and uncertainties as we understand them in the ecosystem. Obviously no one has the ability to fully understand the long term uses and misuses of their systems; however, legally speaking, ownership of ether and use of the reference client itself should be classified the same as use of bitcoin and bittorrent. Thus you are liable for the things you do whereas the developers, speculators and general users in the ecosystem are not.
Distributive ownership of dubious things is another fascinating legal topic that is quite relevant to people in the bittorrent sync and tor communities as well. It is really unclear how the law addresses an actor that simply relays content without purpose or direct knowledge- especially if the content is encrypted for example. In a client server model, generally this concern is addressed by a central entity compelling the server to shutdown usually on a sliding scale. This course isn't possible in decentralized networks nor have campaigns to attack random nodes been terribly effective.
All this said, bad actors will quickly learn- as they are with bitcoin- that the transparency of a blockchain will remove any long term sense of anonymity from their activities. The blockchain is a perfect, honest accountant that will keep accurate books. The blockchain is considered an admissible ledger. Nodes can collect IP addresses of their peers in distributive networks. Yes there are defenses, yet in an age of prism, one must have considerable domain skills to keep everything hidden. Thus most won't and this is why law enforcement as a whole are warming up in certain respects to things like bitcoin and blockchain based ecosystems.
