If you mean overlaying your data atop Google, say a small dataset
expressable as KML, that should work A-OK. If it's pure vector data
being rendered client-side, tiling wouldn't be an issue at all. But of
course, that's where we leave MapServer Land and get into Google Earth,
Google Maps, etc.
If you mean "how did Google do it?" on their basemap I don't know
entirely. They seem to have avoided (or later corrected) a lot of
tile-edge artifacts. Their mechanisms probably included a) a mapping
engine that positions labels to geographic points; b) large-scale
meta-tiling with terabytes of RAM; and c) a large staff of personnel for
QC and a few years of correcting reported issues.
