hi sA,
I've been reading in chapter 8 of the thesis, pages 99-102 and thereabouts.
he is creating a bridge between the canonical loop gravity we are familiar with (SU(2) Ashtekar, Thiemann and the rest) and spin foams, you and I talked about this earlier I think. it is fascinating to watch the bridge being constructed

Am getting a feel for this scaffolding vectorfield c

in chapter 8 he seems to get a version of the theory which is intermediate between canonical LQG and spinfoams so that he can go either way----but so far I haven't begun to look at how he gets to spin foams, only the derivation of usual LQG

looking forward to resumption of conversation about this on your return next week

so far I have no reports from AEI conf.

Me neither. Thiemann promised to send me his talk (which was not on the schedule), but I don't know if it will come by email or snail.

Sounds fascinating about chapter 8. There's a lot of sniffiness over on s.p.r about LQG does not support Lorentz transformations and I wanted to post, "Hey, I know about some covariant QG, wanna see?" But I didn't. Leaving in about an hour, as soon as my daughter gets back from work.
