Query: Non-perturbative renormalization of HQET and QCD   We discuss the necessity of non-perturbative renormalization in QCD and HQET
and explain the general strategy for solving this problem. A few selected
topics are discussed in some detail, namely the importance of off-shell
improvement in the MOM-scheme on the lattice, recent progress in the
implementation of finite volume schemes and then particular emphasis is put on
the recent idea to carry out a non-perturbative renormalization of the Heavy
Quark Effective Theory.
