This program should really be considered dead. If anyone is motivated
to care about it, time should be spent on a new implementation.


The old TODO list follows:

------------------------------------------------------------

eliminate global variables
	clean up command processing
		fix "send" command
	clean up option processing

add empty encrypt hooks (layer over ring buffers)
flushout --> use nullsink

fix ring buffer so it allocates more buf instead of overflowing

put tracing back in

authentication?
