Capture all queries and modify them (2.3.0 release)

[Chema]

Hello:

I'd like to know if is possible to capture all queries performed with
iBatis framework (2.3.0) and modify them.
It would be like a "SQL proxy".

I could to change the iBatis sources but I'd prefer to know if there's
another way using some classes implemented by iBatis

Thanks !

Regards
