I did a system for monitoring security cameras.  The boss said
efficiency in transport was the #1 priority because it limited how
many cameras could be monitored at a remote site.

I did it by defining a number of binary records and writing a method
to read/write each type with DataStream.  It is conceptually simple --
COBOL think, and had almost no overhead. I could have written a
program to generate the Java code to read and write each method given
a data description, but the formats were stable enough I never
bothered. There were heart beat packets in times of no traffic to let
each side know if the other were still live.

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
