Well, as long as the documentation at
http://www.gsmworld.com/technicalprojects/wp-content/uploads/2012/04/snow3gspec.doc
is sufficient to do an actual implementation, it shouldn't be too hard to write the
necessary code with a GPLv2+ compatible license - the actual spec is very short
(6 pages).

Commercial implementors of the algorithms will need to demonstrate that they satisfy approval criteria specified in the Restricted Usage Undertaking and formal permission to use the algorithms will need to be obtained by way of signing the Restricted Usage Undertaking and paying the EUR4,000 administrative charges that applies to non-members of the GSMA.

Beneficiaries of the 128-EEA3 & 128-EIA3 algorithms must also be licensed by DACAS. DACAS grants royalty-free licenses under those patents under separate written license agreements and subject to other terms and conditions which are believed fair and commercially reasonable. DACAS reserves the right to refuse or withdraw the license to/from the parties that refuse to license, or claim unfair, unreasonable or discriminatory royalty rates for their essential IPR. Implementors can apply for the ZUC patent license here.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
