what about doing this as an Opera widget and drop all these USELESS ONE PLATFORM ONLY formats ?
Opera widgets are the basis for the widget standardization process at the W3C, and they work on all platforms : Windows, Linux, Mac OS, Nintendo Wii, Archos, ... and soon on mobile phones ....
Oh and if you worry about having to install Opera to use its widget, don't worry. Installing Opera makes little difference than installing an incompatible widget player. Beside although it includes a standard compliant browser, mail client, bitTorrent client, newsreader, rss/atom reader, widgets player, notes, ...Opera is still smaller than most standalone widgets players.
