[Q] Completely disable WiFi on rooted Honeycomb Sony S. - Sony Tablet S

I have a situation in which I would like to completely disable WiFi functionality. In other words, the user should not be able to connect to any network regardless if WiFi is on or off in the Settings. Is this possible by modifying the file system?
It would be nice too, if WiFi could be re-enabled later with adb.
Thanks in advance.

maybe
system\etc\permissions\android.hardware.wifi.xml
<!-- This is the standard feature indicating that the device includes WiFi. -->
<permissions>
<feature name="android.hardware.wifi" />
</permissions>
not tested yet

Can't you simply turn off the Wi-Fi in Setting as in normal case?

Thanks for the replies.
I tried messing with the permission values in the xml but was still able to connect.
@Kermit33 - My situation is that I have kiosk tablets in retail stores and don't want associates to download the OTA for ICS, and want to prevent them from connecting to Wifi at all.
I am currently implementing condi's solution of renaming Automagic.apk to Automagic.apk.bak, but wanted some extra assurance they wouldn't be able to update.
I decided to just configure the tablet for kiosk, and send them out with Settings.apk disabled so they wont be able to add a WiFi network at all.
Thanks.

Look into blocking the tablets via the router's settings. Using each tablet's MAC address, you should be able to block them from connecting to the router. You should also be able to set the router to block access to Sony's info.update.sony.net web site from where all of the OTA updates are downloaded. Blocking access to Sony's web site will keep the tablets from being updated but will still allow access to other Internet web sites.

Thanks Cat, I'll try that out.

Or, using titanium backup, freeze the system update app.

Thanks for the replies guys, so here's an udpate.
I ended up trying a lot of different things but managed to disable wifi with a custom /system/build.prop.
Before:
wifi.interface=wlan0
ro.ethernet.interface=eth0
ro.ethernet.autoEnable=yes
After
wifi.interface=
ro.ethernet.interface=
ro.ethernet.autoEnable=no
Also set
ro.sony.update.server=info.update.sony.net
To
ro.sony.update.server=
Rebooted and within the Wifi settings, it simply states "Error" after trying to connect. Within WiFi settings, the option to add a WiFi network is disabled. See screenshot below.

Update:
So this works on rooted ICS as well. All that is really needed for HC and ICS is, in /system/build.prop
Change:
wifi.interface=wlan0
To:
wifi.interface=
From the command line or batch:
Code:
::Remount /system as writable
adb shell "su -c 'mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p2 /system'"
::Search for anyline containing "wifi.interface" and replace entire line with "wifi.interface="
adb shell "su -c 'sed -i 's/.*wifi.interface.*/wifi.interface=/g' /system/build.prop'"
::Optional, remove sony udpate url
adb shell "su -c 'sed -i 's/.*ro.sony.update.server.*/ro.sony.update.server=/g' /system/build.prop'"
Reboot for changes to take effect.
