I would like to have very very basic estate functionality for servers without a Monitor license (I'm thinking Express instances on developer's station, sandbox instance without any real databases, etc.).

It would only be to keep visibility on them, so that we don't need to keep an inventory in a separate source. If the edition and version could be included that would be even better but of course nothing about disk usage / backups / jobs, etc.

I realize that this is essentially asking for something for free but I would venture that keeping visibility on all instances might lead of future sales.
