Well, after some struggling I finally managed to creat *.zip files.

I can install and activate both pvr.tvh (0.9.5) and pvr.hts (1.9.31) on kodi and watch TV. There does not seem to be any difference in performance or behaviour. With both the switching between channels does take up to 30 seconds, much, much longer than before (tvheadend and kodi are on the same computer with i7 CPU).

pvr.tvh gives an error message:
20:18:57 T:140065158178560 ERROR: AddOnLog: Tvheadend Client: pvr.tvh - malformed dvrEntryAdd/dvrEntryUpdate
20:18:57 T:140063715358464 ERROR: Previous line repeats 2 times.

pvr.hts also gives an error:

though in either case I can wathc live tv and records without any impact (as it seems)

But obviously, GLIBC 2.17 is not required. My Ubuntu precise 12.04 has glibc 2.15, and this seems sufficient. Would certainly increase the user base, if you make the glibc requirements less stringent.
