Great idea - this could be really useful.
I get lots of errors running on OS X 10.5.2 though:

Any ideas?

Cool - its all working now. Is there any cache expiry for tiles or is it a case of deleting the tile directory?

Last public post on this toy, I promise. Some people thought it might be useful so it's here now: http://svn.openstreetmap.org/applications/viewer/pymap I haven't tested how well it performs (Simplicity was the first goal), but it will certainly be better than a crappy wlan. It would also be trivial to make it update old local tiles on demand. I agree that this would be ideal to showcase OSM maps e.g. at conferences where WLAN is existent but horrible. spaetz ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

No expiry so far, but it would be easy to make it so. All the pieces are
ready, basically.
Until then, just deleting old tiles must do.
find tiles -mtime 30 -exec rm {} \;
will delete all tiles that are older than 30 days, for example. Use that
command with great care.

I have tested it on Windows XP and the only problem is that images are not shown, everything else seems to be in place. I don't think it's because of using / instead of \. Apparently the HttpServer only delivers the first bytes of the PNG files, and then closes the connection. I have tried to add the file length and proper file type in the header but it still closes the connection too soon. wget.exe is unable to get the whole image file either. I'll keep on trying, lol On Windows, all Python read/writes have to be opened with rb/rw instead of r/w. Changing Line 36 to: f = open(installpath + path, rb) Might do it.
