IMHO, such a discussion should also consider the user perspective and 
distinguish  two types of TCP connections: Those that result into user-
observable delay (e.g. HTTP) and those that don't (e.g. SMTP). Such a 
modification could be made configurable by applications: Web servers (and 
browsers) could use a larger initial window while SMTP servers/clients could 
use the current approach.
