I guess that depends on the application and what "serious" means :-)

As Kevin hinted at, one can use Erlangs' distribution protocol without
using automatic connection handling. OTOH, if you for instance need more
security than Erlangs distribution mechanism provide, it might be wise
to invest in a custom protocol anyway. FWIW, I imagine the data
serialization/deserialization functions could be reused.
