conditional puts and deletes not possible...

[cesardevelopment]

It seems that because every attribute value (except 'id') is always written as array (multi-value) to SDB that conditional puts and deletes are not possible - (AWS docs state that multi-values conditional updates on multi-values will fail). It looks like the gem needs a complete re-conception and re-write because of this - or - is there a simple monkey patch that could be applied could incorporate this feature ??
