Why do we use Titanium? Technical hurdles or staff decision?

[tristantio]

Is it something such as the EQEMU server only being able to encrypt/decrypt packets with the Titanium algorithm or is it necessary for other reason, such as compatability with the custom shipped files (dlls) that are needed on p99?

How much work (or is it simply not allowed?) would it be to reach the point where the Sony provided official client/download would connect to and work with p99?
