Would you be willing to > discuss those? yes, certainly. the text i quoted from the 2010 resimprove draft was the result of implementation experience, and touches on necessary details, which are at the moment missing from serve-stale. i'll be very happy to discuss these, though regrettably, i could only be in prague for sunday, and so i'll miss any side meetings or working group discussions this time. no disrespect is intended by my absence, i had other obligations. -- P Vixie
