realtime in UED allows surfaces with a lightmap already=
 (prerendered) to accept realtime light from a new pointlight,=
 and to move existing pointlights around. i don't know exactly=
 how it's done, but i suspect it's a texturing method like bert=
 mentioned... when you do move or put a new light in, it casts to=
 all facing normals in its range even thru solids that would=
 otherwise block it.
