I've heard good things about AeroFS (YC S10), which is sort of like Dropbox except it runs on your network of computers. It's a peer-to-peer filesystem.
A couple years ago I wanted to publish an iPhone app under a business name but I was a solo developer with no clue about the legal aspects of starting a business. In the end what worked best for me was registering a DBA / Fictitious Business Name, which for a modest fee and a trip to downtown allowed me to pick a business name to use in the app store.
If you go the single member LLC route (which I found in my case was overkill), note that California has an $800 minimum tax. If you register in Delaware and want to do business in your local state (e.g. open a bank account), you'll probably have to register as a foreign corporation and pay any applicable local taxes in addition to Delaware's fees.
If he wants to be missing, there might not be much you can do. If you know where he lives, you can find someone in the area to knock on his door and check if he's there. In some cases you can also call the non-emergency line of the local police and ask for a "welfare check" where they will drop by and check on the person. If the family suspects something is wrong, they can file a missing persons report with the police.
In my experience, simply changing environments may cause an increase in productivity. Even if the new environment isn't strictly better, you still get a boost until you get acclimated. This might be crazy, but some sort of random rotation between various work environments might yield a sustained improvement in productivity.
This was really interesting. Every week, the teams have two meetings. One in which to brainstorm, to forget about constraints and think freely. As Lopp put it: to "go crazy". Then they also hold a production meeting, an entirely separate but equally regular meeting which is the other's antithesis. Here, the designers and engineers are required to nail everything down, to work out how this crazy idea might actually work. This process and organization continues throughout the development of any app, though of course the balance shifts as the app progresses. But keeping an option for creative thought even at a late stage is really smart."
