If you do scripting languages at all, check out SL4a (Scripting Layer For Android). It gives you access to the android API in each language - Python, Perl, JRuby, Lua, BeanShell, JavaScript, Tcl, and shell. It comes with its own basic editor, but you can specify a different editor if you have others installed - I've used the Jota text editor with it. Get SL4A here: http://code.google.com/p/android-scripting/ I've build a few basic interactive android apps with this setup, and various console-only scripts. You should be able to configure it to store the files in dropbox or similar to get auto-syncing too.
