I'm not really sure I understand, but if the members are intended to
be separate threads, you should definitely have one connection per
member.
If they are just different tasks that a single-threaded service will
perform, it's more of a toss-up, but I think the idiom today is to stick
with local connections. Keep in mind that ADO .Net maintains a connection
pool where it lingers to disconnected connections and then reuse them
if there is a request for a connect with the same properties within
some timefram (60 seconds, I believe).
