Karniq it isn't as hard as you are making it sound. At most they would need to add an export function to the character loading code where the export function would then dump the relevant character data to an ordinary sql type db. This is exactly the approach I've used in professional datamining/recovery where an OODBMS is involved. Now it may well be they can't afford to pay someone to do the necessary work, but it is not an insurmountable or even difficult technical problem.
[EDIT: duh they already *have* an export - the character web api - technical problems my rear end]
