My requirement is that I have "items" with different states. I need to do all kinds of different things based on the states of these items (send emails, store files, update internal applications, etc). The problem is that the application that updates these statuses is third party, so I can't update it; furthering the difficulty is the fact that only half of the organization is using this system and the other are using it's future replacement. I do have open access to both of the databases used.
My plan is to add a message to a SQL Service Broker Queue with and ID and the status via a trigger on each representation of the Item table. Then, call a CLR procedure from the SSB activation procedure that adds a message to a publish queue via NServiceBus.
This all seemed to be going well until I tried to register my assemblies in SQL with CREATE ASSEMBLY:
Msg 10327, Level 14, State 1, Line 1
Warning: The Microsoft .NET Framework assembly 'system.web, version=2.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a, processorarchitecture=x86.' you are registering is not fully tested in the SQL Server hosted environment and is not supported. In the future, if you upgrade or service this assembly or the .NET Framework, your CLR integration routine may stop working. Please refer SQL Server Books Online for more details.
etc. etc. etc.
CREATE ASSEMBLY for assembly 'System.Web' failed because assembly 'System.Web' is not authorized for PERMISSION_SET = UNSAFE. The assembly is authorized when either of the following is true: the database owner (DBO) has UNSAFE ASSEMBLY permission and the database has the TRUSTWORTHY database property on; or the assembly is signed with a certificate or an asymmetric key that has a corresponding login with UNSAFE ASSEMBLY permission.

First, I want to know if this is a completely crazy idea. I want the messages processed in order and added to the queues asynchronously. NServiceBus provides a host application that makes it very easy to spin up a new publishers when needed. The alternative seems to be to write a windows service that monitors the SSB queue and then publish. I'd just like some opinions or advice. Thanks.
