Sleeping in someone else's home is dangerous, but the dangers can be lowered by having a reputable service vouch for people. Most of the couch surfing I've seen done it through reputable websites and not (something like) Craigslist. However, I do not believe such a service exists for vehicles.

In the scenario, are any of the 2-3 PC's storing the files or are they all streaming from another location?

When we went, we priced a hotel room (and wound up staying in the Paris Hilton [though they call it the Hilton Paris] outside the Eiffel tower); apart of the priceline was an addon for a nighttime tour of Paris from the river. It was great.

One thing I immediately see as "wrong" is Windows 8. :-P

Mavis Beacon?

Are you looking for the calendar to sync in real time? Real-time (or near real-time) is convenient in that if you loose/damage/break your phone inbetween manual tethered syncing, any changes are lost. If you use the google services, the changes are synced every X amount of Y automagically.

Another piece of advice; if you're not sure about a lens, rent it for a weekend before you blindly purchase one. This way you can get a feel for it before plunking down big money.

SBSettings is awesome

Refurb MacBook Air?

I'd be extremely careful about doing this and think that it's a bad idea. What if there's an accident? What if you're inadvertently a drug mule because the car was packed with coke? Who do you call if the car breaks down or is stolen?

Picasaweb or the new Google Plus. Lets you set albums to private (so only people you specifically invite can see the photos, even if someone forwards the link to a "non-approved" person) and will let you upload photos/videos. Best of all, it's free.

Running a G device and an N device on the same wireless network will bring the entire network speed down to G.

Have you tried Mint?

Each port can run at a different speed but the speed is determined by the device connected to it. Once you go from a device that's 10/100/1000 to 10/100, there's no going back (I mention this because you mentioned you have a variety of switches).

Defron:

What if you nailed a thin piece of wood to the door frame and then attached the weatherstripping to the wooden strip?

Get a better son :-P

Headless doesn't necessarily mean that there isn't a GUI. Windows Home Server is designed to run headless yet is a full fledged version on Windows that you can RDP into.
