What OS X Bit Torrent client is best for working with remotely?

Apparently it has a command line client as well. Who knew?

Transmission is awesome. It has a web client as well. You can add torrents via the web client. I use it at home. It works great.

Definitely Transmission. The web client lets you either specify a URL for the torrent or upload one directly. It's super slick. You could, of course, just use VNC/screen sharing.

you can also set transmission to watch a folder for added .torrent files. It might be more secure for you to upload .torrent files via SFTP to your remote mac, if you're worried about that traffic being spotted.

I second Transmission. The webGUI is pretty decent so give it a whirl if you want. I personally have Transmission constantly checking a particular folder for new torrent files. So I ssh to the machine and drop off whatever I want to start downloading. Works like a charm. If you have DYDNS you can do it from outside your house too.

Deluge (and probably other clients) lets you designate an 'auto-add' folder where you just drop torrent files into to add them to the client, which is anxiously waiting for anything to appear in that folder. Coupled with SSH access, the remote torrent interface is pretty no-fuss. SFTP in to drop off torrents, SFTP in to pick up the completed downloads. I have deluge daemonized and can connect to it by a remote deluge front-end, web UI, or even via tunnel and VNC, but I always end up just using SFTP and the auto-add folder. It does the job with as few steps as possible.

Also consider rtorrent/wtorrent. I have heard of people purchasing space on remote servers for the purpose of torrenting, and this is the interface they use. It sounds like more work to setup but definitely less overhead and you can mess around with your own scripts too. rtorrent is available on MacPorts but I usually grab http://libtorrent.rakshasa.no/wiki/Download. I've never bothered with wtorrent, but if you want a nice interface, then wtorrent is essential (rtorrent's interface is godawful if you have more than a hundred torrents).

I hear a lot of support for Transmission. Does the remote Mac need to be logged in for the webUI to work? See, I'm used to the linux setup I had whereby after booting up, I knew that within about a minute, all the required services would be running, the DynDNS would have updated and I'd be ready to go. Can the same be said of Transmission on OSX? Though I suppose, if I log in through SSH there's nothing stopping me from running the client from the terminal to launch it then switching to the webUI, is there?

I doubt you'd have trouble running the webui in the background the same as you did with your linux setup. just "sh command.sh &" and throw it in an init script if you like. Furthermore, if your now-home machine is Mac/Unix, you can use http://fuse.sourceforge.net/sshfs.htmlto mount a directory over ssh and set up the bt client to save files to it. Automatic copy-back, though I supposed seeding could be a drag.
