I remain confused by the purpose of this project. SQL Server 2008 provides Centralized Management Server which allows you to register all of your servers in a single location and execute a single command against all of them from one location. This is all built into the product. At a minimum, shouldn't this be the mechanism used to gather your data rather than creating a server table and looping through it to execute DML commands.

There are also mechanisms for data collector, which will gather data and place it into a "management data warehouse".

Seems like you're re-inventing a more cumbersome wheel here.
