"Serious question, are the backcountry devices fast enough/allow enough bandwidth to work on servers? (Say restart a service? Move files?)
Just curious…not sure I'd actually take it backpacking with the weight and concerns about electronics issues and for other reasons not appropriate for this thread. :)"
Right now? It'd take some creative engineering.
I believe Iridum has a throughput right now of like… 10 kilobits per second under ideal situations.
Think of that as an extremely slow modem dialup speed.
Apparently Iridum Next should be online by 2017 if they stay on schedule, and if memory serves they'll support 1megabit transfer speeds. Which is actually fast enough to do stuff, even at the RDP level. I imagine it'll be hella expensive though.
As far as services and moving files… If you could console in via SSH or something like that there's no reason why you couldn't issue text based commands. The latency would be killer and might be a deal breaker, but I'd say it's entirely possible.
Edit: I may have been overly optimistic about the Go's throughput. As the BPL article explains, a 32kb photo took 5 minutes and a couple restarts to send.
IF I was going to try to use this with corporate email, I'd seriously consider setting up some rules on my mail account so that only the most important stuff goes to my inbox while I'm out. Otherwise I'd spend hours downloading the thousand emails or so that I get every day that are generally crap.
For the OP, I'd say this is your only back-country solution, and it's not going to fulfill your needs. It's insanely expensive, and if you're modifying a couple meg file, it's going to take like 3 hours to download and 3 hours to upload. My honest-to-god suggestion is to find a resupply or stopping point that will have some kind of internet you can tap into and scheduling a point on a day that you will be "live" and let your work know that this X hour period is when you have reliable connectivity. Any time you hit a summit or a point that overlooks the central valley or maybe the 395 feel free to pull out the phone and look for a signal. The Sierras are getting more and more saturated and I was surprised where I got signal. However, I wouldn't rely on that.
The tech isn't there, and the price point certainly isn't there right now.
