Adobe FDK under wine? Or similar FOSS tool?

[Vasile Gaburici]

Editing OpenType feature tables with fontforge is a big PITA. Adding a
locl table to Linux Libertine, see
[https://fedoraproject.org/wiki/L10N/Tasks/Ro_fonts#Linux_Libertine],
took me three hours (testing included). And that just for the regular
font. Parts of the table are (or rather should be) common between
files, but fontforge doesn't support that, so I have to start over for
the bold and italic!

This presentation
[http://blogs.adobe.com/typblography/atypi2006/slye_lisbon-05.pdf]
should give you an idea what the right tool for the job is like. The
good news is that Adobe FDK is free (as in beer). The bad news is that
Adobe makes only Win32 and OS X versions of it. Does anyone here have
any experience with it? Does it work in wine?

Also, does anyone know any FOSS tool that uses Adobe feature files or
similar text based files (please not that thingie that converts fonts
to XML). Fontforge is supposed to be able to import fea files, but
currently it's broken (does nothing); maintainers have been
notified...
