I would like the ability to predefine parameters in some fashion and then display them on the edit host page. I would like, if possible, to be able to define a default value and then choose between an entry box to change this or a drop-down with multiple pre-defined choices. I should also be able to say this is a mandatory parameter. Oh, and if we're really pushing it tying these parameters to included classes would be even better.

When adding a new host this would make it much easier to pass off the process to junior staff by making it impossible to miss a parameter or set it to the wrong value. If I include ldap then it would be nice for it to then require a value for $ldap_role for example.
