Yes i saw you wrote something about async shell-command ;)
I will have a look.

Some simple thing like that can call any external process async:

,----
| (defun tv-async-process (process &rest args)
|   (apply #'start-process process nil process
|          args))
`----

==> (tv-async-process "xterm" "-e" "lynx")
#<process xterm>

or

==> (tv-async-process "firefox" "http://www.emacswiki.org/cgi-bin/wiki")
#<process firefox>
