Stupidity or sequences?

Hi all,
I think most of us has seen someone trying to be smart or trying to gain
database independencies by not using oracle sequence but instead roll their
own system by using a table, and a row for each "sequence".
Almost every attempt on this I yet have seen has been plagued with row lock
contention or other concurrencies, scalability zero...

Have anyone actually seen some implementation of this kind work  when load
increase?
