My thoughts:

Have one general logonbatchfile in which you copy the kix executable and dll's to the workstation if not yet available. Yes I know you can make it smarter with version-control and things, but this is the idea:

LOGIN.BAT:
IF EXIST(C:\NETTOOLS\KIX32.EXE) GOTO RUNKIX
:COPYKIX
C:
MD \NETTOOLS
COPY \\SERVER\SHARE\KIX.ZIP
UNZIP KIX.ZIP

:RUNKIX
C:\NETTOOLS\KIX32.EXE \\SERVER\NETLOGON\LOGIN.KIX

:END

In the kix script, you can use the @RAS macro thingy stuff tool macro!
