Disable Facebook Applications on the Network

Is it possible to only block Facebook apps but not facebook?

We have a relatively liberal computer use policy.  Facebook is allowed but I want to disable the facebook gaming and (to a lesser extent chat).

Is there something I can do to allow people to comment and update statuses but disable Farmtown  and the like?

Also is it possible to disable gmail chat (not the google chat app because I won't let them install it)?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you could try blocking the address http://apps.facebook.com , i m not sure about the chat though.

I ve just tested adding apps.facebook.com to the restricted sites in internet explorer and it wouldn't load farmville, not sure about other browsers through i ll have a test later when i have more time :)
another alternative is to add " apps.facebook.com" to the hosts file of the computer (ive just tested this on win 7 but should work on xp as well) the advantage of doing it this way is you could have the address route to an internal webpage saying don't play games...

I just found this:

Disabling chat features for your entire network

We understand that it's sometimes necessary to disable instant messaging services on a network. If you need to prevent users on your network from chatting, we suggest blocking DNS look-ups to the following domains by returning

    * To block Gmail chat: chatenabled.mail.google.com
    * To block iGoogle and orkut chat: talkgadget.google.com
    * To block the Google Talk client and other desktop clients: talk.google.com and talkx.l.google.com
