Thank you Alex! I'll take a look at DumpRequestHandler and see if I can pull pieces from there and from MLT.
I was also looking at DirectUpdateHandler2 to try and tease apart the logic for parsing an incoming json (or xml or whatever incoming format is). Do you think that's worthwhile? My thought was that this is what backs "/update" and that's how I'm loading my json files. It looks like DirectUpdateHandler2.split() might be relevant too.
