Resetting License from Actionscript 3

Question

Hi,
Currently I have a video whose license has a playback window set:
http://help.adobe.com/en_US/flashaccess/2.0/javadocs/com/adobe/flashaccess/sdk/rights/Play Right.html#setPlaybackWindow(long)
Now when the player gets this license and initiates playback, then the license expiration starts then.  What I want to be able to do is within the player, I want to be able to reset that license, so that I can download a new license and restart the playback window countdown again.
Is this possible?  I tried looking at DRMManager (http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/drm/DRMManage r.html), but it doesn't have anything pertaining to resetting/clearing out the license from Actionscript.  The two ways I know how to clear out my license is to do it manually by:
1) http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager08.htm l
or
2) By clearing out the license files/directories.
I would like to be able to clear out a specific license from within the Actionscript 3 environment.
Any help would be greatly appreciated.  Thanks!

Hi Eric,
Thanks for the feedback.  Is there a way to specifically set the license expiration date relative to the playback time, so the playback window and the license expiration time are the same?
According to the docs http://help.adobe.com/en_US/flashaccess/2.0/javadocs/index.html?com/adobe/flashaccess/sdk/ license/License.html , there's no way to set relative license end date, so it seems very impractical to somehow set it to the same time as when the playback window ends.
To give you some context on what I'm trying to achieve, I'm trying to make it so that a viewer of the media content periodically grabs a new license to watch the content (let's say 24 hours).  This is so that the license server can say at any moment the user cannot grab a new license (let's say we do that 60 days after the content was initially released).  Ideally we would only have to run the media content through the flash packager only once with the proper license variables  (and obtain an encrypted media file and voucher) so that the player can only use a license for 24 hours and continually request updated licenses as they expire.  Is this possible to do this?
