How About Connection Pools

I have been doing a little research into connection Pooling with OCI and 
I was just wondering if the concept of a "Connection Pool" would fit 
into the DBI spec someplace.

As we already have DBI::Apache and "connect_cache"  would it just be 
redundant to add this  "connect_pool" as the present functionality can 
be 'Bent' to that way?

Say something like this

$DBI->connect_pool($pool_name,$data_source,$username, 
$password,$min_connections,$max_connections,\%attr);

The idea being one could create two separate pools at the Apache level 
one for lets say "Read_only_Users"  and one for "Read_Write_Users" and 
use connections out of the pool.

Or am I just creating something that no-one else will use??
