Sharing ActionWebService::Struct across several API

Hi,

I would like to know if there is a way to share ActionWebService::Struct
across several API (same rails app of course). I have duplicated the
structs, but:
1/ It’s not DRY
2/ Callers are .NET callers, and each proxy generates structs in
different namespaces, so callers cannot receive an object from an API
and send back to an other without doing ugly casting.

Is there a way to share them?

Thank you,
Jean-Etienne
