Hi, Simon is correct. A byte-range locking implementation for OpenAFS is being funded by Your File System, Inc., under its DOE SBIR Phase II grant. As stated elsewhere by Jeff, there are (or will be) structures for making completed available to the community during the course of the work.
However, my understanding that shared r/w access to sqlite through AFS probably does work, provided you ensure sqlite uses the correct locking style (cf. sqlite's os_unix.c): #define SQLITE_WHOLE_FILE_LOCKING 0x0001 /* Use whole-file locking */ This feature is apparently due to Adam Megacz, who posted briefly about it in 2006. See http://marc.info/?l=sqlite-users&m=116742195016159&w=2 .
