mmmh, maybe im lost, but urxvt supports traditional methods very well, terminology has just "more features"
basically: just select text with mouse to copy, and use the middle button for paste, this should be the standard in all the terminals / consoles (even out to a tty)
that's not a problem in elive you can simulate a middle-click with the touchpad by pressing both buttons at the same time, or if your touchpad don't have phisical buttons, you can still trigger a middle click by doing a tap in the top-left corner of your touchpad
(yeah, more unique features of elive :P)
