Hotswap

Hot swap is useful for more than constant uptime production
systems.  When you are doing development on a system involving 
more than a few modules/processes the startup time can be
significant.  Just starting an erlang node takes a while.  I
generally edit code in one window and then in another I am
running an erlang shell on the system under test in which I 
run c(module) which compiles and loads the new module.  You
then test, edit, test, etc.  This iteration is really fast 
compared to a cold boot of the erlang node and starting the 
processes.
