The MUFI Project website (http://helmer.aksis.uib.no/mufi/) has links to sites of font designers and digital typographers working on fonts with medieval glyphs.
They're at The font page (http://helmer.aksis.uib.no/mufi/fonts.html) but it might be interesting to check out the whole project.
We are currently working on a first proposal of medieval characters (or characters for medievalists) to be presented to the Unicode Consortium.
