GBM Forum member sockapoke has linked to an interesting little find that is new to me but maybe not to others. NoteLab is an open source digital note taking application that lets you take and store your notes on Linux, Mac, or Windows. It stores the Ink in Scalable Vector Graphics (SVG).
I’ve downloaded this and given it a quick try this morning and it seems to work as advertised. Note that there is a caveat when using Windows and the “press and hold” feature of the Tablet bits. Here’s a link to that.
