then it should be perfectly possible
Now how would you like the test to end?
I can think of 2 ways:
1. you disqualify the flash and give a message 'not allowed'
2. you try to fix the flash, replace / strip away tags and use the fixed version
I know too little of flash, to know if #2. is possible and still have a working flash,
but there are plenty of good functions for search and replace any code.
See for example [man]str_replace[/man] and [man]preg_replace[/man]
