Oracle Portable Tools

After several Windows XP "Blue Screen of Death", my working laptop has led in a Tech Support Center (finally it could be a hardware problem, not an OS, don`t blame about MS).

Now I may temporaryly work with an alternate laptop, that has been used in the past, and would be used in the future by others. So, I cannot (might not) install any application on it (Oracle Client, telnet/ ftp client, code editor, etc.).

So, starting with current scenario, I pose myself next challenge:

Could I find some Portable Tools that let me work with Oracle Databases, mainly on UNIX platforms using ANY computer, with no installation, and at minimal time required?

I assume you'll find easily many Windows computers per one linux or MAC, so I restrict my search for Windows environment applications.

I found some solutions:

Telnet Client: PUTTY portable, easily portable, just copy putty directory in a pendrive and leave it in your pocket. Unfortunately, I have found no alternative for Putty Connection Manager, as it needs .NET 2.0 to be installed on the windows system.

FTP Client: Filezilla Portable, which you can take your server list and settings with you without leaving any information behind.

Oracle Client: SQL Developer. You can export your connections in a XML file and copy it to your USB folder to follow you anywhere.

Password Management App: Password Safe. You can store and manage all your Databases and machines passwords using this application. Latest version can be installed in 'green' mode on a USB pendrive. If you store your passwordsafe file on same pendrive, you will be able to access your environments without memorizing all passwords.

Code Editor: Notepad++. You can edit your code using this open source editor that supports sintactic staining for main programming languages.

That's what I found up to now. Any helps and comment would be appreciated.
