Off-line mobile or desktop? Application or Browser based?
A lot of people use a format called MBTiles to store offline caches of
tiles locally. Generally with OpenStreetMap tiles this is quite an
acceptable use. GDAL/OGR can read mbtiles along with other tools for use
in an application you make.
For Google maps they have very specific methods of caching locally using
their api (might be mobile device only).
Hope that gives you some direction to start looking.
