[TxMt] select to copy and middle-button paste?

[William Scott]

One of the nice features of iTerm and Aqua-Emacs is that selecting  
text copies into the paste-buffer, and clicking the middle mouse  
button pastes in text from the buffer, as with X11 programs.  (That,  
and focus-follows-mouse are the two features I miss most from other  
unix operating systems).

Is there a way to do this in TextMate, and if not, is there any  
chance it might one day be implemented as an optional feature?
