I've been thinking I'd like to resurrect the Hop Check proposal (because after further reflection I think it would be useful, even if not perfect):
for debugging/support? +1 [...]
Before I post an updated version, does anyone have requests for data they'd like to see included in the data format?
A bidi flag (for s2s) and the raw certificate data for both dialback and external auth. Probably also whether an SRV record was resolved or the A fallback is used.
And keep in mind that most s2s connections still aren't bidi, see the list archives from 2007 for some discussion ;-)
