just my two cents: I’m also under the impression that github is kind of too-big tool. I was thinking along the lines of a wiki system; is there one that the IETF operates for such purposes? It would give the opportunity to see the change history and multiple people may work on it simultaneously; similar to github but geared more towards texts. However, if there is no wiki then github surely is a good solution as it is readily available.

Although I think github is more mechanism than we need, I can't find a good alternative for posting a current charter so, yes, please put the proposed charter on github.  I've attached the initial draft charter from the BoF request and a revised charter with additional WG logistical info.

Please send text with a concrete proposal?

As far as I know, we're going with dnssdext.  Other suggestions can be considered.  I expect it will be in INT area.
