There is a Kerkis package for TeX (tetex-font-kerkis). Nowadays, the author of this font publishes TTF and OTF files, quite suitable for on-screen display. The license, however, is a bit ambiguous, possibly even a removal candidate. http://iris.math.aegean.gr/kerkis/ (see the License subsection).
This one should have been passed through fedora-legal before inclusion.
Definitely. That license is waaaay too vague as is.
We'd need to know if:
- Modification is permitted
- Redistribution is permitted (this is implied, but not explicitly
granted) 3. Redistribution in embedded documents is permitted
That's just for starters. The commercial copyright "advertising" clause is also painfully vague.
Someone motivated (and likely, fluent in greek), should email the copyright holders and suggest that they either clarify their license, or consider relicensing it with an established free license (e.g. the OFL).
I will contact the author to clarify the above. Thanks for the guidelines.

And here is the gist of the communication with the maintainer. The current license of the font is in the License.txt file in CTAN: http://www.ctan.org/tex-archive/fonts/greek/kerkis/License.txt
The Copyright of the fonts belongs to the The Department of Mathematics of the University of the Aegean, Karlovassi, Samos, Greece
If you want to use this font family in commercial work (like in books), we strongly request that you include in the Copyright section the fact that you are using "Kerkis (C) Department of Mathematics, University of the Aegean".
"The Kerkis fonts and kerkis.sty are licensed under the LaTeX Project Public License, version 1.3c or later. See http://www.latex-project.org/lppl."
He also gave positive answers to the primary questions and has relaxed the advertising clause (from the former *must* to *strong request*).
Is there something else that needs to be communicated or can we consider this font OK?
Thanks,

The outlines of Kerkis fonts look like those of URW Bookman and URW Gothic. Kerkis has different a style of figures than URW Bookman and has more character coverage. If Kerkis fonts are derivatives of URW's gsfonts, then the license should be the same as gsfonts. URW Bookman and URW Gothic are GPL'ed.
