How proficient are those users? If they're not too proficient you might be able to hide the source using uu{en,de}code, eg uuencode your script, put the coded text into a variable in another script where you decode it on start into a temporary file, which you then execute.

Name
uuencode, uudecode - encode/decode a binary file for transmission via mail
Syntax
uuencode [file] remotedest | mail sys1!sys2!..!decode
uudecode [file]
Description
The and commands are used to send a binary file by uucp (or other) mail. This combination can be used over indirect mail links even when
is not available.
The command takes the named source file (default standard input) and produces an encoded version on the standard output. The encoding uses
only printing ASCII characters, and includes the mode of the file and the remotedest for recreation on the remote system.
The command reads an encoded file, strips off any leading and trailing lines added by mailers, and recreates the original file with the
specified mode and name.
The intent is that all mail to the user ``decode'' should be filtered through the program. This way the file is created automatically
without human intervention. This is possible on the uucp network by either using or by making be a link to instead of In each case, an
alias must be created in a master file to get the automatic invocation of
If these facilities are not available, the file can be sent to a user on the remote machine who can uudecode it manually.
The encode file has an ordinary text form and can be edited by any text editor to change the mode or remote name.
Restrictions
The file is expanded by 35% (3 bytes become 4 plus control information) causing it to take longer to transmit.
The user on the remote system who is invoking (often must have write permission on the specified file.
