7    ##    + added support to get remote objects via backend via 'guid'
8    ##    + renamed '_loadBackend' to '_loadRemote'
9    ##    + constructor now accepts additional options:
10    ##      + remote: try to get object via '_loadRemote' ...
11    ##      + oid: use the given identifier as an 'oid' when doing '_loadRemote'
12    ##      + guid: use the given identifier as a 'guid' when doing '_loadRemote'
