What is "The Internet" TCP/IP or UNIX-to-UNIX ?

	I think its generally agreed that FTP is used for file transfers,
but unfortunately the option exists to attach files within an email thanks
in part to MS/AOL/Compuserve and numerous others long ago. I believe its due
in part to ease of use for those that aren't technically inclined to know
better, and make things "easier" for them (harder on others). 

Kind of like cattle, if you leave a hole (or make a hole) in the fence
eventually it will be used and the only thing you can do is build a fence
outside of the hole to keep the heard from getting to far.
