Hi Jimmy,

This is great to see :)

We've been running an embedded RP 'public' service here for a while, as
a follow-on from 6NET; the problem is the definition of 'public'.  Our 
application is available to the JANET community, since the UK academic 
IPv6 service supports it, but currently we have no availability beyond 
that because GEANT have not turned on embedded RP on their Junipers.  
Unfortunately this also means we can't test your application from here.

Our routers and JANET's are currently Cisco.

I think embedded RP has fantastic potential, and I understand that DANTE
will enable embedded RP on GEANT when they feel it is fully tested to 
their satisfaction.   Perhaps if Internet2 has positive experience on
Junipers it would help to relay that on, though at the tast TF-NGN 
meeting I think deployment was announced for March/April, so not long to 
wait :)
 
As soon as it is enabled, we'll be very keen to test your channel and
advertise our service, and heopefully show the value of embedded RP for
streamlining multicast deployment.  Once we're all 'joined up' it would
be nice to have a range of applications to showcase.
