We have got the usual issues with the shockwave flash games at our place as well. One of my ICT Tech. have developed a client/server application that runs in the background that blocks the shockwave flash games.
It does this by using the hash value of the game and then when the game is played in IE it closes this down if it matched the hash list. There is also an option to close the Adobe Flash player.exe to be killed as well. This does not affect the active x plug in so its okay.
It doe rely on creating a file with a hash value so he has also designed a hasher program which will generate the hash value from a directory which contains SWF games.
The program can also be told to copy a file (swf) to a central location that is not the list. This will capture all the swf files so it may include the legit flash movies as part of thier coursework. It doesn't remove the file just copies so if its a a game (manual check required) then you can create a hash value of it.
Using the hash value gets around the problem of users renaming the files to something else.
The program checks the file list on the server every 10 mins (can be changed in the ini file options) and updates its own file every 5 mins.
I don't know much of the other technical details but i will get him to tell you guys more and release to educational establishments once its all sorted out.

Ye we mainly had them coming in from excel, and well in all honestly not sure on that one I don't think so, but then blocking all activex here didn't cause any problems at all not totally sure why the kids would need it anyway, from what im mainly aware of activex is mainly used for flash.... Feel free to correct me?
"Ideally, we'd want to be able to have a black list (or a white list) of allowed SWF embedded files.. but this is not easy. " - I dont think thats possible at all would be good thought although we have moved to open office here so havn't looked into the lastest office GPO templates.
Hows the program progressing Ash?
I've just got back from Holiday yesterday so i'll update you guys on Monday. I'll inform the technician to post the beta of the program here so people can test it out etc. As always the manual and documentation is still in development so the instructions may be simple.
I am just preparing the files for distribution, I've written some basic (very very basic) documentation.
I'll post a little later with where you can download the package from.
I appologise to anyone who looks through the source, it really is spaghetti code and badly commented.
Ok, here are the files needed. They are zipped up, so if you unzip directly to your packages directory (q:\applications\) you will end up with a directory called gamekiller2
In here are the files needed. Documentation and zips of the source for visual studio 2008.
To use the program as is, update package list, allocated it to stations, and create folders for the logs/hashlist
Need to create...
w:\mcplist (hidden read only folder)
w:\mcplist\logs (student writeable)
w:\mcplist\logs\tocheck (student writeable)
w:\mcplist\hashlist.txt (created with mcphasher)
Ok, adding an attachment doesnt seem to work. (6meg .zip file, maybe too big?)

Could you not place them on your FTP server for us to gain access even with password if needed. ;-)
TerminatorX seems to do a resonable job with things like that, new version out too apparantly.
