My USB keyring needs a ftp client

[unicorn]

Hi
I need a ftp client that I can run from an USB key ring or a USB portable harddrive, without installing it at the machine where I connect my USB device.
The FTP client... if there is such a thing, should be easy to configure on the fly, regarding PORT and PASV mode and such, must have an editable favourite list that gets saved at the USB device only, should be able of handling a queue. Hmm, basically it should be sort of UltraFXP or FlashFXP but without installation (and if possible without leaving traces in the registry of the machiny. As you understand I want to be able to plug it into machines running Windows 2000 or Windows XP.

Suggestions?

and ok, hugs to everyone I haven't spoken to for a while! Seems as I turned away from computers in favour for cameras for a while...
