I recall at one point there being a plugin that gave effectively an activerecord model but without the table requirement. Hmm.. it appears it's no longer maintained but there was this: http://stackoverflow.com/questions/937429/activerecordbase-without-table-rails
If that doesn't work for you, you can always write out dryml input tags for your special class that don't have to do the lookup to see what to name a particular input. And yet another approach, would be to encapsulate this model within a normal hobo model. I would guess you have some model (or models) that are related to this in some way.
