Hi everyone, long time no post!
Wow, a lot has happened to PDO while I was looking the other way for a minute. I hope I will soon find the time to bring PDO_FIREBIRD up to date with all the recent changes.
What would be a reasonable deadline for this (in relation to 5.1) ?

As I've said before in our discussions about PDO, I am not very happy about the apparent 'impedance mismatch' between Firebird and PDO. If PDO is turning out to be a least-common-denominator solution like most abstraction layers, it's going to be impossible to ever provide the features that the original Firebird/Interbase driver does.
For instance (these issues have been pointed out by me before):
- Firebird has transactions over multiple connections [no JOINs between databases, but atomicity/consistency across multiple DBs]. There's no way this will ever be supported in PDO due to the way it was designed;
- running concurrent transactions off the same connection;
- named results;
- the whole service API (inquiries about the server/database/users etc.);
- event handling;
So if the intention is to ultimately replace the Firebird/Interbase driver with a PDO one, a lot of work has to be done. And PDO *will* have to be changed to allow for the more exotic features of Firebird.
