Rob, you just gave me a great idea for something to do with a Raspberry Pi!
I like the e-radiogram to Winlink idea Austinrob.
I've been looking around for a few years now for an open source project that would:
- Modify Squid to strip everything but HTML
- Use mod_gzip for the above when talking to remote servers that support it (most do, now in 2012)
- Work on a low power platform (Raspberry Pi is the current winner.. former: Cradlepoint routers, Linksys WRT54GL's, etc)
The basic idea is you're working with small bandwidth. What can you stick in between a person with an iPad/notebook/etc and a BGAN terminal ($1 per megabyte) or similar high-cost bandwidth to maximize your efficiency? Letting people email their family with webmail minus the tons of data that usually flows between (hard with https)? What about keeping your retail environment alive that uses many GB a day on a slow VSAT link (part of my job).
If you are an amateur radio operator check out HSMM-MESH. It doesn't do the above but with OpenWRT and it's meshing stuff it's pretty nice and is catching on. I just wish there was a simple ready to go project that could be installed anywhere (heck let's get crazy and say your Sprint android phone still works and nobody else's does; make it a hotspot, add this strip-it-all Squid package and you're done! People see 1995 Internets!)
