Editing one word in a file on 50nodes simultaniously

Hi.

I have 50nodes connected together and i can do rcp,rsh on those nodes and using home grown application i can execute command parallelly on all nodes at a time.
Now my question is i want to replace one field in one file on all nodes. The file and field exists on all nodes but the contents of the file or not same on all nodes.
Can some one please help me with some script.
example,
/etc/passwd file exists on all nodes and "bin" user exists on all nodes. what i want to do is locate user "bin" in all nodes and replace it with "binuser"

NAME
rcp -- remote file copy SYNOPSIS
rcp [-46p] source_file target_file rcp [-46pr] source_file ... target_directory DESCRIPTION
The rcp utility copies files between machines. Each source_file, target_file, or target_directory argument is either a remote file name of the form ``ruser@rhost:path'', or a local file name (containing no ':' characters, or a '/' before any ':'s). The following options are available: -4 Use IPv4 addresses only. -6 Use IPv6 addresses only. -p Cause rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignoring the umask(2). By default, the mode and owner of target_file are preserved if it already exists; otherwise the mode of the source file modified by the umask(2) on the destination host is used. -r If any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a directory. If path is not a full path name, it is interpreted relative to the login directory of the specified user ruser on rhost, or your current user name if no other remote user name is specified. A path on a remote host may be quoted (using '', '"', or ''') so that the metacharacters are interpreted remotely. The rcp utility does not prompt for passwords; it performs remote execution via rsh(1), and requires the same authorization. The rcp utility handles third party copies, where neither source nor target files are on the current machine. SEE ALSO
cp(1), ftp(1), rlogin(1), rsh(1), hosts.equiv(5) HISTORY
The rcp command appeared in 4.2BSD. BUGS
Does not detect all cases where the target of a copy might be a file in cases where only a directory should be legal. Is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host. The destination user and hostname may have to be specified as ``rhost.ruser'' when the destination machine is running the 4.2BSD version of rcp. BSD
