Not that I know of.

I think it would require substantial effort.  It entails implementing
the following options from 1588:

  16.1 Unicast message negotiation
  17.5 Unicast discovery
  17.6 Acceptable master table
       [ Since this is very similar to the unicastMasterTable of 17.5,
         you can kill two birds with one stone. ]

We already have some support for subscriptions and notifications, and
so you would naturally build upon that.

Thanks,
