Hmm. If storage continues to improve as fast as it has been, once the space infrastructure is there, this might be cost effective. We have a lot of data to send.
In particular, we are going to need to have a local cache of the internet on Mars. At best, the average minimum latency is 225 million kilometers / the speed of light = 12.51 minutes.
Vast data barges, roaming the solar system, keeping everyone in sync....
Building an interplanetary Internet is going to be very, very fun.
On a related note, never underestimate the bandwidth of a truck filled with...
Well I was going to say blueray disks. But the cheapest I can find bluray disks are 3 cents per gigabyte. 3 TB harddrives are easily had at 5 cents per gigabyte. If the data only needs to go 60 miles, then 120 drives ($18,000) in a truck would get 1 TB/sec, or 8,000 mbps...
Ouch. I'll go with a megabit connection. Once upon a time that sort of thing worked for bulk data ;)
