I am also a very happy daily user of dvtm and I recommend it. I use it like such: dtach -A ~/dtach-socket -z -r winch dvtm -M
I used tmux before dvtm. I didn't have any real problems with tmux, but I like dvtm better because I find tmux to be too elaborate, too many options, too many keybindings, too much functionality in one program. I found this article helpful "Three-way mini shootout between GNU screen, tmux and dtach+dvtm" at http://chithanh.blogspot.com/2010/07/three-way-mini-shootout-between-gnu.html -- http://www.fastmail.fm - Access all of your messages and folders wherever you are
