Subject Firebird - Interbase connection

I did not know where to put following queries, so I am asking this to both general and support forums.

One of our application tool/software is using Interbase as the Database server, which is, of course, a licensed RDBMS.

Our tool works with both Interbase and Firebird 1.5.6.

I am aware that Firebird is open source SQL RDBMS.

I have few doubts which are as follow :


If we use Firebird for our future use, is the latest version of Firebird would be compatible with our tool ?
we have to make major changes in our source code to be able to work with Firebird 2.* ?


As Firebird is an open source RDBMS, is there any licensing issue attached to it ?
I mean, Is using only Firebird would/should eliminate the licensing thing attached with when using Interbase as an RDBMS with our tool ?

OR Am I understanding it completely wrong ?

I hope you understood my queries and your reply would clarify my doubts.
