It would be nice to have a "project initialization state" per host.

When adding a new project, each host would have a bit turned on that indicated that BAM should read the list of projects attached from the host. Once the first connection with the host is complete, the initialization flag would be turned off, and the state of the host would be recorded in the BAM database. You might want to make this true only if an account was found instead of created. If the user works the checkboxes in the BAM UI for selecting which hosts are attached to the project, BAM would write the state to the client instead.

This would solve the occasional problem where BAM detaches a client when a user makes a mistake in entry when attaching to an existing account.
