+ * knowing whether the host is lumping multiple applications into a
+ * single "client"), the point of the exercise is just to make the
+ * C_Login()/C_Logout() semantics work as expected in the presence of
+ * multiple applications.

+ * should use the public hal_rpc_*() API.
+ *
+ * In particular, the breakdown of which functions go into which

+ * sure that the right functions get linked in the right cases, and

+ * In theory eventually we might want a fully general mechanism to
+ * allow us to dispatch arbitrary groups of functions either locally
+ * or remotely on a per-user basis. In practice, we probably want to
+ * run everything on the HSM except for hashing and digesting, so just
+ * code for that case initially while leaving the design open for a
+ * more general mechanism later if warranted.
+ *
+ * So we have three cases:
+ *
+ * - We're the HSM, so we do everything locally (ie, we run the RPC
+ * server functions.
+ *
+ * - We're the host, so we do everything remotely (ie, we do
+ * everything using the client-side RPC calls.
+ *
+ * - We're the host but are doing hashing locally, so we do a mix.
+ * This is slightly more complicated than it might at first appear,
+ * because we must handle the case of one of the pkey functions
+ * taking a hash context instead of a literal hash value, in which
+ * case we have to extract the hash value from the context and
+ * supply it to the pkey RPC client code as a literal value.
