I was looking at your Route10 product, but it looks to be consumer-heavy,
at this point time. I run stuff like BGP in my home network (as I have
MPLS-to-the-home delivery) and PIM-SM, would be cool if you folks supported
some DC-fabric features on Route10 in the future with FRR as the daemon or
something.

One thing I'd like to mention, Route10 should have a good NAT
implementation to support EIM-NAT for TCP/UDP to allow P2P networking to
work over a NAT box.
Additionally, support NAT Hairpinning for user's LAN subnets to allow
intra-NAT traffic to work over STUN discovery, this eliminates TURN traffic.
Small to large-scale CGNAT deployments around the globe is something I've
been consulting for a few years now. I'm happy to potentially beta test
your products, if you'd like, for best practices conformance with very
specific RFCs.

BQL would be good to have for long-term viewpoint, perhaps your Ethernet
driver provider, could patch it up for BQL support and that would be a good
foundation for FQ_Codel on your Route10. MikroTik has FQ_Codel, but lacks
BQL, and they refused to listen to Fran and Dave Taht, so perhaps you folks
are our only hope :)
