Dec 1, 2017 at 0:37 comment added Yemon Choi MatthiasLudewig: Well for one example: if M and N are infinite-dimensional Hilbert spaces that are irreducible G-modules for some locally compact group G, then the only G-homs from M* to N would be scalar multiples of the identity, which can only be Hilbert-Schmidt if they are identically zero. I guess that similar considerations may apply for certain non-irreducible reps, given the title of the article that @MarcelBischoff refers to

Nov 27, 2017 at 19:36 comment added Marcel Bischoff As far as I understand, the problem is that "even in the simplest case this space will be dense", see p253 (2) in Vaughan Jones, Fusion en algèbres de von Neumann et groupes de lacets
Nov 27, 2017 at 17:04 comment added Yemon Choi I thought the main point of the Connes fusion product was to tensor two bimodules and obtain a _bimodule? In any case, have you looked at Andreas Thom's article tac.mta.ca/tac/volumes/25/2/25-02abs.html which might implicitly address your question?
