I think Anyterm might be better at operating at lower bandwidths, but ajaxterm blows it away in terms of pure simplicity to set up. If you’ve got your own server, all it needs is some python, and then some apache magic. it starts up it’s own server, so theoretically you could run it standalone, but I’m not certain of the wisdom of this.

I’m mostly impressed with how simple it is to make it work. You can run it as root, and it’ll use “login” or you can run it as any user, and it’ll run “ssh localhost”. The running as a normal user is probably safer, but you have to have some sshd on the system.
