Make sure you guys read the
policy on sound systems, and communicate to placement the details of what kind of wattage you're looking at, as well as the approximate hours that you intend to be operating. It's important for them to have an idea of what you'll be doing, so they can work out an idea of what neighborhood you might work in (for the area you're looking at the posted limit is 300 watts). Camps that have achieved exceptions to the sound guidelines (ie Distrikt, Duck Pond) have done so through both years of neighborhood evolution and working with the placement team.
If you're doing different parts of your infrastructure in different parts of the country, yeah you've potentially made it a lot more complicated. Hopefully from a project management standpoint you can divide things up in ways that don't depend on each other (for example stage at site A, yurts at site B, etc), that way you don't need to worry so much about getting those components together at a staging area in advance. Communication is key though, keep in regular touch with the leads from each site and share pictures and progress reports with each other (a private FB group can work great for those purposes). It's important not only for you to feel like people are holding up their end, but it's important for the other people to feel that as well. Plus good comms gets people excited about the bigger picture.
If things aren't divided up quite so easily (for example part of a stage at site A and part at site B), then it does get a lot trickier. My advice is to have the secondary group deliver the goods to the camp's home base (or wherever the bulk of the project in question is being done). Assuming that once the components come together, there still may be more work that needs to be done, you'll want that to be at whatever you guys consider to be your full shop (where you'll have more tools etc). The alternative is to either find and rent some space to work in Reno, but that can get expensive and you're potentially away from your full shop, or to bring all your gear and materials you anticipate needing to the playa and working, but can be not only be tougher to do but extremely painful if you end up having to send people back out for additional supplies/materials.
I've been in camps that had project and production management issues, and would rather stick to doing something smaller well than something larger that turns into a clusterfuck. That can cause a ridiculous amount of stress and fracture even the best of friendships, I wouldn't wish that kind of anguish on anybody. For us, any project that isn't completely modular needs to come to our home base pre-event. Needless to say, as we've evolved over time as much as possible is completely modular. That, and for a number of our remote campmates (more than half come are coming from around the world), they make their plans to travel to the camp's home city for their final prep and work before departure.
