SmartFTP for ISP!

I have found that nowadays there are no way to do law aknowledgement ("I agree", "do not agree"), before got connected to FTP server.
I am administering my FTP server [i am using proftpd from www.proftpd.org].
Is it possible in the near future to do some FTP++ protocol enhancements say between proFTPd and SmartFTP, which both would support law aknowledgement dialog box?
