  We present several steps towards large formal mathematical wikis. The Coq
proof assistant together with the CoRN repository are added to the pool of
systems handled by the general wiki system described in
\cite{DBLP:conf/aisc/UrbanARG10}. A smart re-verification scheme for the large
formal libraries in the wiki is suggested for Mizar/MML and Coq/CoRN, based on
recently developed precise tracking of mathematical dependencies. We propose to
use features of state-of-the-art filesystems to allow real-time cloning and
sandboxing of the entire libraries, allowing also to extend the wiki to a true
multi-user collaborative area. A number of related issues are discussed.
