Do not confuse OpenSER and (Iptel) SER.
db_mode 3 on Iptel SER is the READONLY DB mode (in CVS HEAD) which upon 
start reads data from a database and afterwards drops the connection.
The somewhat same behaviour can be achieved using save_memory()
on OpenSER.

The cacheless approach you are looking for has been implemented in
the userloc-cl module as pointed out by Nick.
Please take into account that synchronizing the MySQL cluster
will result in performance penalties but on the other hand
you should have everything in memory courtesy of MySQL ;)

What number of parallel registrations are you looking at?
There are probably better ways of doing this than MySQL Cluster,
