LPC: Life after X

The problem is that applications (and toolkits, antialiasing, etc) have bloated the number of round-trips required. In my (admittedly anecdotal) experience, modern applications (including a current emacs) run *way* slower over a network than similar programs did in the 1980s. Everything has been designed and optimized based on the assumption that the X server is on the same machine as the client.
