Over the last two years, applications to use the tau decay package TAUOLA in different Monte Carlo chains for LHC and LC applications have been developed, and found useful for the ATLAS and CMS collaborations in establishing significance of signatures for new physics with the help of tau leptons. The physical constraints necessary to be fulfilled by different sections of the simulation packages are discussed. Methods of how to apply the package in new C++ and FORTAN applications as well as how to improve TAUOLA with the form factors of Belle and BaBar simulations, which will become available only in the future, will also be discussed in the context of multitude of applications with generators such as PYTHIA, HERWIG, and one based on fixed-order matrix elements. Tools such as MC-TESTER necessary to keep track of the physics content of the package will also be discussed. Recent updates of the PHOTOS package for radiative corrections in decays will be also discussed in the context of applications such as W mass measurement at the Tevatron and LHC. Some examples relevant for future phenomenological applications for the LHC and LC will be also be mentioned.
