Multi-clienting = logged in with more than one character, only one active at a time, you switch between them. Only a problem if you're afk macroing with them. Otherwise perfectly acceptable.
Multi-boxing = logged in with more than one character, using special software to cause all to be active at the same time and controlled simultaneously by the same keystrokes.
The program used does not affect the datastream per se, therefore cannot be deemed illegal - however the use of it in UO is considered to be macroing, which is illegal (I think)
