ok, i'll give that a shot then if only to get my head around odb's.

gotta admit that a lot of my bias towards the rdb is based on the fact
that mysql (our weapon of choice) has proven itself to be an incredible
speed daemon (i mean, they sacrifice transactions, which i don't need, 
in the name of speed). 

but don't worry, i'll go into this with an open mind... 

and thanks for setting me straight :)
