I don't really get it, wspd is currently intended to be configured as an
external daemon listening on a unix domain socket same as fssd does,
'setup_named_pipe_socket' that handles all of that is essentially what
has been changed in rpc_server.c, the necessary changes needed to
support that are imho pretty minimal. The alternative if I understand
what you mean is to duplicate that functionality (basically the server
loop) in wspd itself.
Also, It is also possible to run in embedded mode, an instance per
client kindof matches the way WSP appears to work in that a client can
open the pipe mulitple times (for related queries), it may even be
possible at some stage to somehow leverage that per-userness wrt tracker
(although currently I have to admit I don't have any idea about that).
Note: the code that supports the embedded service is similar to and
additionally reuses those changes in rpc_server.c

I am not qualified I guess to say more than I think the changes
(especially related to the if(s)) are pretty small, I think the little
bit of infrastructure added was what I understood metz previously
suggested (but of course I could have misinterpreted)
