Oh god. Imagine Illyan's memory chip acting up every time he spent too much time in Vorkosigan house, as saturated with magic as the place is. Imagine him getting a head injury and having to remind Cordelia not to perform any quick-fix spells, for risk of sending the technology totally haywire. Man and what if some of Barrayar's resistance to modern tech was the result of widespread magical abilities among the inbred upper-caste population? That could be super cool, in an even-more-fucked-up-class-relations sort of way. Hmmm.
