This scenario gives an alternative to the cosmological constant or quintessence. In [astro-ph/0106274] the authors claimed that this proposal is strongly disfavored if not ruled out by the existing data on Supernovae, Cosmic Microwave Background and clusters. We show that the work [astro-ph/0106274] contains incorrect statements in the theoretical part, and, moreover, we argue that the main conclusions of the work concerning the comparison with the data are premature.6 pagesAstrophysicsHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
