Hi Michael,

Yes, I did all and it wasn't comfortable enough for me. I tend to make an
'Internet-free cure' in the summer and when I returned,
I had parts of my emacs configuration I didn't remember what exactly they
did (tramp config among them).
I had been experimenting with the flexibility of (interactive) before the
break and I decided to go that way (instead of RTFM,
I'm an engineer by education ;-) ), because I find it clean and cool. And I
came up with this way of doing things...

But I'll give the 'canonical' tramp configuration a chance, don't worry,
/PA
