May I ask for your motivation to use a different database? I'm personally also not convinced of the mongodb + nodejs approach of nextepc-hssd. No disrespect to Sukchan here, it's mainly a question of different taste / preference. Given the excellent built-in Diameter support in Erlang/OTP, if I was to implement a "real" HSS for larger/realistic public networks, I would probably recommend to do it in Erlang, using mnesia as database backend. For smaller, more embedded "network in a box" systems, something more self-contained like a C program with sqlite3 seems like a good idea. This is what we did in osmo-hlr.
