[Tilecache] Problem to support OSM

[hz hanks]

Hi, All

I was asked to set up a cache server with seeding function, so I
picked tile cache. It's working well now with WMS.

The problem is that, according to some licence issues, we need to use
the map data provided from OSM. And we don't want to set up OSM server
by ourselves.

Is there any simple way to solve this problem? For example, can we
just add an entry in tilecache.cfg with some URLs to OSM server (e.g.
http://a.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png) and let it
work just as WMS?

Does anyone have a suggestion? Really appreciated!

Best,
Hanks
