Explosive runes via SMS/e-mail - is it possible

[Capt Spanner]

Looking at the RAW it probably isn't. :-(

Can anyone interpret the rules such that I *could* send someone an explosive runes SMS or e-mail?

Checking D20 Modern would probably be your best bet for the interaction of spells and technology.

I was gonna bring up that there aren't rules in D&D 3.5 on SMS/Text Messaging, since it's electrical data and not REALLY sending someone a message. It's also possible that the receiving device would have to be...well...formatted correctly?

d20 modern would be a great place to look though theoretically.

a class feature from the Techno Mage Advanced class from Urban Arcana lets you do this.
Online Casting

At 8th level, the Techno Mage can cast spells through electronic devices, including cameras, cell phones, and modems.

If the spell requires the caster to be seen, then the target must see the caster, if it requires the caster to be heard, then the target must be able to hear the caster. Range is determined from the caster to the pick-up device (camera, keyboard, etc.) and then from the device to its target. The space between keyboard and monitor, or camera and screen, is not considered. The Techno Mage must be able to see or otherwise be able to determine the location of her target (“person at the keyboard” is a suitable target). Spells cast online are less effective, such that the target gets a +4 circumstance bonus on saving throws.
