[AccessD] OT: (kinda) FTP Question. Heeeeelp

Considering the fact that this is the most talent group professional that I
know of, I have yet another Command Line question.  I have searched high and
low, and can't seem to find a solution.

Does anyone know of a good Multi-thread upload FTP client, that also has a
solid Command Line interface:

Stuart helped me work out the main section of my "project", and I really
thought this was going to be the easy part..

After I have the split zip in a folder, I need to be able to send the folder
using the same bat file via a multi-threaded upload. 

I can find great Multi-threaded FTP clients, but they have terrible Command
Line support, OR I can find a great Command Line FTP Client but it doesn't
have Multi- threaded uploading... 

I have looked at:

CuteFTP
SmartFTP
Filezilla
FTPRush


FlashFXP

... HELP.....
