Re:Issues with such networks generalize to Mars
by DarkFencer (260473)

In the very long run, after we colonize Mars and possibly the Moon, latency issues will become even more severe. It will be interesting to see whether we will simply give them separate networks or have those networks as part of the internet. If the second occurs, we may need new protocols to deal with the large latency and related issues.

We already have networks with latency comparable to round trip Earth/Mars connections. Its called Time Warner Cable.
