Hi, Thanks for the replies - You are right that bulk upload will work, I just have an aspiration to getting it to work closer to real time so want to explore other possibilities.
At the moment I have not tried to get mod_tile working, but am using tilecache on my home server to generate the tiles (because it is very easy - just a simple python program and minimal configuration - this will seed down to zoom level 12 nice and quickly. I then have another instance of tilecache running on the commercial web host that caches tiles from my home server to give a quicker response (provided the tiles have been accessed previously). I will do a little wiki page write up on how it is configured, because it took a bit of doing to get the projections working so that they talk to each other properly.... It seems to be working, but needs a bit more testing because sometimes it seems to take a very long time to produce a tile - this may be my home server putting its disks to sleep to save power, but I haven't checked. Disk sleeping is not a feature I would want to turn off though, because using my old laptop as a server is working quite nicely power-wise - I think it takes less than 20W normally, which is not too bad.
