Hello,
Thanks for the inquiry regarding OPC development work.
This is currently something that's on our development plan, and we have dome some background work on it.
At this point however, we would welcome a community member or end user client to partially sponsor this kind of development work in order to see it through to release.
If this is something that you might be interested in, please contact us directly, and we can exchange some information and details about this project.

Regards,
