TCP doesn't work well over wireless links that have high packet loss rates.
Arguably the right way to solve this is with link-layer transmit or FEC, 
but you don't want to do that for some kinds of traffic.  And now that
TOS has been deprecated it's not clear (at least to me) how an application
can label its packets so that the link layer won't do this.

Whether you think HTTP works well over high latency links probably depends
on how you use it - especially the granularity of interaction that your
application needs.  For many applications the TCP connection setup already
causes a significant degree of latency.

Just the obvious ones.
