Short story made long:
Roughly a year and a half ago, I really started craving a good IDE. The one thing that has always prevented me from buying is the fact that none of them run on Linux and support SFTP tunnelling.
In talking to a few of the IDE manufacturers, and their PMs, I've found that they don't think it would have any bearing on their sales. Macromedia has built it into Dreamweaver so obviously there's one.
Every dev I work closely with uses vi over ssh. I'll probably buy the first IDE that does finally support SFTP tunneling and runs on Linux. I'm curious to find out if any of you are in the same boat. Anyone?
