Yes.

Remote ids are not globally unique, they are only unique within a resource, 
and there items in different collections may even have the same remote ID. It 
is purely an implementation detail of the resource, I don't think normal 
clients should use it.

If you really need opensync-specific information for each Item, add an 
Attribute to it when you create it. You can put any data you want into an 
Attribute, including an opensync-specific ID.
