Apologies, having a day mostly out. That is indeed the package I am using. Glad you found it.
Just quirks, like if you cd to an absolute path 'cd /' it will cd to the local path not the remote one.
There are quirks, I'm sure. But that is one that actually makes sense. I do sometimes wish it were easier to cd to the root of the remote, but not often.
I usually prefer having the main remote directory open in dired and a shell session in another buffer. I prefer to work in a Posix shell as AFAIK eshell does not do at least one of: IO redirection, piping.
