Bibus-Biblio is an excellent opensource bibliography program (http://bibus-biblio.sourceforge.net/) which can run from a usb key. It works very well from the usb but does leave stuff behind in the registry. It would be great to be able to use this in a truly portable way without the registry. It also works well inserting citations into OOo or MsWord but would be even better if it would work with portable OOo on the usb. I wonder if anyone has any experience with this program on usb or any idea if it is possible to overcome these two issues.
