I am planning to use tilestache as the tile server (map server) for serving maps to both iPAD and web clients.
I plan to generate tiles by Tilemills and store tiles in a Sqlite database (mbtiles) and serve it using Tilestache.
My questions are:
(A) How scalable is the solution, for example the project may have 200 IPAD users in field?
(B) Is client side local caching supported or do we have to pre-load tiles in the local storage?
(C) Most important, can any such mobility solution using tilestache be sited to see the performance results?
