May I introduce you to https://tools.ietf.org/html/draft-morton-tsvwg-cheap-nasty-queueing-00 ?  I'm also in the process of expanding the LFQ draft.  I think they show that HW acceleration *shouldn't* mean just dumb FIFOs.

I'd actually be rather interested to see what a Raspberry Pi 4 with a GigE USB3 dongle tacked on can cope with, now that it has native GigE through a direct PHY connection instead of via a USB2 bottleneck.  That would be in the rough price range of a basic wifi router, and I've already got a Pi 2B running as an SCE endpoint.

Any idea which shops I should look in while I'm in Montreal?
