C'mon guys, If you can store data in a thing, DM should be able to wrap it...
I mean, if you can store key value pairs, we could *easily* write something the yields relationship-type mappings, right? I'm also keen to start using a proper object database like gemstone/s with merb... (maglev hm? :))... because then we can write proper ruby objects for our model with proper relationships and not use this cobled SQL crap anymore. The thing then, though, is that we'd need some legacy-backuppy- database support thing... for when we have clients that require the database to be able to be backed up and restored to some sql type thing. I personally detest SQL backed databases.
