According to 10083036 (and a couple of other threads), its possible to
specify the import server in the registry.

Would it be possible to add this registry entry into the MSI file?

A transform won't work, as I'm trying to use the Agent Distributor Utility
(and there doesn't seem to be a way to add addtional lines to the installer
to point to an MST file).

The reasons for this are:
1) entering in entries for ZWSIMPORT arn't really feasable in our
2) Hosts files are icky, and require another distribution ahead of time
3) Same problem as above if I try to push the registry key prior to
installing the agent

With the simplicity of the tool, it would be nice to be able to simply point
to an IP address range, install the agents, and the installer handles
pointing to the import server.

Is this feasable using somethign like ORCA to edit the MSI?
