To be fair, a small hard-core crowd of four original acolytes that started
it all is recovering from a till-3-AM town-bash in celebration in Singapore
;-) Some may caught me sleeping day after in open area meeting, my co-chair
was even worse for wear ;-)

Hurray!

Just the beginning, we're talking recharter now, accepting tons interesting
pending work into the group and looking fwd' to standards track and many
years of interesting applications in the field ...
