Ya, that would definitely be useful for web-based tools. And if a tool similar to the Ailia/Bleh Spell Editor was made to edit the Table version, I think it could really make a nice option for spell file management. Plus, this would give the option to use mysql commands to mass edit the spell file if people wanted to do that for any reason.
The only thing I would recommend for this system would be a really simple way to convert the spell file to the table and then the table back into the spell file. Otherwise, custom servers might have issues when trying to make sure that their custom spell files match the custom spell files that their players downloaded for their server. If a tool was made similar to the Ailia/Bleh one for the Table version, it would be very nice if the same tool would also convert the file to table and visa versa.
Since the spell data is loaded globally when the server starts, I doubt this would be possible. But, it would be really cool if we could have a command that would let NPCs use any spell effect with custom values at any time. Essentially making a custom spell in real time via Perl. I think the command could use the fields in the table and then also set a value for it, and then just use the effects from the source for those fields. So, maybe something like quest::spelleffect(type, value), or maybe an extended version like quest::spelleffect(type, value, range, target_type, duration_ticks, pet_name, icon, "description", "msg_cast_on_you", "msg_cast_on_other") or something like that. Kinda off-topic idea, but sounds like fun to me
