I think that this is right forum to post this little announcement: we just released new product, named FogLamp. It is very simple application which has only one purpose: convert Fontographer database files (versions 3 and 4 are supported) to FontLab files.
FogLamp is available separately (for both platforms) and in bundles with Fontographer and TransType Pro. Combination of Fog, FogLamp and TransType Pro allows to build Fog-based font-editing environment which can generate OpenType fonts in both "flavors" as well as any other font format.
More information is available in press release.
