You don't need anything else to create this database but a trusted spectrometer and physical access for many displays. It's nothing else but measuring the spectral distribution of the display primaries.
The tricky part was to describe the spectral sensitivity characteristics of the sensors (which should be done individually on every individual instruments -> or could be batch averaged to save time over quality...) but if I get it right then you didn't replace this data in the sensors (but X-Rite did it with NIST certified tools, so nothing to worry about...)
Of course it would be the best to do it with reference grade spectros in a lab but I think the traveling ISF/THX calibrators could also help with this: any time they calibrate a display which doesn't have a database entry then they have to use a spectro. If CalMan finds an entry in the database then the user can decide if he uses it or he creates his own i1d3 correction with his own spectro. If he uses his own spectro then he can decide to upload the results to the database (and next time he will be able to recall that, no need to use the spectro again for that particular display model, not even he uses a different i1d3). As more entries get uploaded, they can be automatically inspected and sorted/averaged. And as the database grows, almost every popular display models would have a trusted entry (-> no need to use spectros on the filed except some rare cases).
I think your software could ignore the EDR files in the EEPROM of the instrument and use a custom (downloaded) one. Or is this correction step hardcoded at driver level? If so, then it's a shame (for X-Rite). Even if you don't create this database, the on-the-field colorimeter corrections should be done with this method anyway (instead of the old matrix based method which is strictly bounded to the actual colorimeter).
Of course, all of this would only work with the i1d3 (at this time - but old colorimeters could also be spectrally characterzed in a lab, you just can't store the data in the instrument's EEPROM. But here comes another online database which stores the colorimeter characteristics for the serial numbers... * Doesn't it sound like "endless possibilities"? This is the "revolutionary" in this new colorimeter, the spark of these ideas...).
