DTS - FTP Task - SQL Server 2000

Hi
Could any body tell How to download files from Internet where Source file server is using SFTP (Secure FTP)?
Note: I am able to configure and download files from Internet where Source file server is configured for FTP using FTP task in DTS Package.
Thanksone option is to download a client for SFTP, create a CMD files with commands and execute under xp_cmdshell

i.e. look at PSFTP
