Ah, I think you misunderstood part of what I was trying to say --
which is that `file-readable-p' can be very slow when you *are*
connected (when I'm not connected it returns in a fraction of second,
so that's not a problem)

The reason is that that ange-ftp implements it rather inefficiently.
Instead of just listing the file in question it lists *all* files in
the directory.  That's a lot of data if the directory contains
thousands of files.  In the example from my previous post doing
`file-readable-p' is ~500 times slower than actually fetching the
file!
