In my experience, it is; most ssh implementations turn off nagle on
"interactive" connections.

Applications which attempt to track mouse movement (e.g., scroll bar
sliders) don't work very well with nagle turned on.  my understanding
is that "animated" widgest typically require 24-30 updates per second
before it begins to look smooth, while the interaction between delayed
acks and nagle cause very bursty behavior.
