Would not it be k00l if there's a Forex aka Foreign Exchange calculator/fetcher of latest rates (off e.g. Nikkei or some banks or financial institutions) utility available in GNOME that allows for REAL-time, instantaneous conversion between currencies not limiting to just those between the USD and Euro but all tradeable world currencies?
Such a piece of software can either be a standalone app or be called upon by integral components of major office suites (e.g. Openoffice.org (Writer, Calc, Impress)), GNOME Office Suite, KOffice); financial management software (e.g. gnucash, gnofin); and even quick note-taking programs like Tomboy in GNU/Linux and the *BSDs or as a useful plugin to web browsers such as Firefox (useful when instant rates conversion is needed for product prices on say amazon.com) or even as a simple desktop applet. Does anyone knows if such an app and/or plugin exist? (preferably aGTK2 one)?
