Login in Flash > then open FTP window?

I’ve got a client who wants a Flash site that would have a “Client Access” area. He already has a number of FTP sites for his clients through Dreamhost. He used cPanel to set up the sites.

Currently “Client A” is able to login to his FTP account by entering a username/password at www.site.com/client_a

I’m hoping it’s possible to enter the username/password in Flash, which would then trigger another window containing the client’s FTP account.

Yes? No? Maybe so?:-/

Did you ever have any luck with this? My client is asking for exactly the same thing with DreamHost.
