Hi,
I saw you are looking for a Telnet/SSH-tool... Since I have hosting, I use WinSCP in combination with puTTY. This way, you can handle files with a GUI and you also have the possibility to use a CUI.
WinSCP is downloadable as installer, standalone and source code. So maybe this can help.

I don't know how life could exist without PuTTy and WinSCP, they are so useful!
You can download PortaPuTTy, which doesn't leave any traces in registry etc, and set WinSCP to store settings in an ini file in it's advanced settings, so you can have a totally portable Unix/Linux connectivity suite everywhere you go!
