After reading this wiki page I have few questions (I admit I haven't
tried it yet).

1) How do you limit access to shared prserv instance?
   Can you define some group as RO, some RW?
   For RO access it would be great to export state from remote PRSERV 
   on first connection and then continue to increment locally (with
   PRSERV running on localhost)
2) If you have slightly different builder (e.g. someone with extra BSP
   or different host distro), then he will have different checksums, so
   different AUTOPR values and you cannot share binary feed with such
   builder, right? I know this wasn't possible (or at least safe) to use
   before too. But it should be more clear from documentation.
3) Is it possible to use OEBasic together with PRSERV or should bitbake
   show fatal error when PRSERV is used toghether with OEBasic?
4) Is there plan to import current PR values from recipes, so that
   bitbake can parse all enabled layers, gather checksum-PR values and
   export it for bitbake-prserv-tool to import it as inital state?
5) Is there plan to remove PR from all recipes or are they ignored with
   PRSERV in use and can stay in for some time? If there is functionality 
   for 4) then we should tag all layers just before PR/PRINC are removed, 
   so someone can create own initial export from last known PR state.

Cheers,
