From the blog:
"Textmate only allows one to use the project drawer if you’re working on a project. Otherwise, there’s no ability to use a drawer or tabs and you’re back to regular multi-window text editing—which stinks. Most people run into this issue while editing files live on a server via sFTP or FTP with Transmit or some other client."
Actually, I've run into this issue plenty of times when working with the *local* filesystem. I bet everyone's experienced this at some point: You end up with lots of files open that don't belong to any particular project, so you have this extra-long Window menu and can't easily jump between open files like you can with project files. It would be nice if TextMate had some kind of "anonymous project" window -- that is, a pseudo-project that looks and acts like a regular project, but instead of representing a folder or specific set of files, it would represent all the open files that don't belong to any project. You know, like BBEdit's file drawer.
"Actually, there are three ways. If Mac OS X could mount a remote sFTP connection one could easily accomplish our goal. It does not. It mounts FTP connections, but they are read-only—so again no go."
However, as has also been pointed out on the list, OS X can mount remote directories via WebDAV, AFS, and NFS. That way, you can create projects on the remote server directly, just as you would on local filesystems. I prefer this solution whenever possible because it's so simple and doesn't need rsync or other special commands.
