Live debugging is possible in most systems (except for many 'modern'
scripting languages), it is the live code _alteration_ that makes it so
powerful.
I've wielded that force in Smalltalk and Forth systems.

Pro: our customers experience higher uptime of their business processes
because only one process is halted in their server and later continued,
as opposed to the whole system being taken down due to a walkback in one
thread.
Con: IT departments -particularly the outsourced ones- feel that a
server with a GUI is unmaintainable and should be verboten.
