1.6 Applicability Statement

The protocol described in this specification is applicable to users of the .NET Remoting Protocol, as specified in [MS-NRTP] in environments that require distributed activation and lifetime management of Server Objects.

CAOs require a server to maintain references to each client object created, which might not scale to large numbers of clients.

The Sponsor mechanism requires that references be maintained from each server to all registered Sponsors. In addition, the server has to individually contact each client with a Sponsor, which does not scale for large numbers of clients holding Sponsors.
