  It is:
,----
| vc-cvs-stay-local is a variable defined in `vc-cvs.el'.
| Its value is only-file
| 
| Documentation:
| Non-nil means use local operations when possible for remote repositories.
| This avoids slow queries over the network and instead uses heuristics
| and past information to determine the current status of a file.
| 
| If value is the symbol `only-file' `vc-dir' will connect to the
| server, but heuristics will be used to determine the status for
| all other VC operations.
| …
`----

  'only-file is non-nil but is not equal to t
  I think this check could be changed to (not vc-cvs-stay-local):


(defun ecb-vc-dir-managed-by-CVS (directory)
…
       (if (or (not (boundp 'vc-cvs-stay-local)) ;; XEmacs doesn't have this
               (not (eq vc-cvs-stay-local t)))
…




  It seems to work well after that.

  ecb-ping-options is by default wrong in many operating systems. For instance GNU/Linux's ping requires -c 1 or -c 4 or any finite number.
  You could use another (ping) function which already knows how to ping on many OSs, for instance:

,----
| ping is an interactive compiled Lisp function in `net-utils.el'.
| 
| (ping host)
| 
| Ping host.
| If your system's ping continues until interrupted, you can try setting
| `ping-program-options'.
| 
| [back]
`----

  (Internally it is doing this:)
,----
|  (defcustom ping-program-options
|   (and (memq system-type (list 'linux 'gnu/linux 'irix))
|        (list "-c" "4"))
`----

  That (ping) does not return the exit status of the program, but a buffer which needs to be parsed.

  Maybe other methods instead of ICMP could be used to check for connection; for instance connect directly to do what you wanted, and in case of connect failure you know there's no connection.
