You can find a list of servers at
http://svn.osgeo.org/gdal/trunk/gdal/frmts/wms/WMSServerList.txt

Find out what a TMS has to offer. Service metadata:

    >>> service = tms.TileMapService('http://maps.opengeo.org/geowebcache/service/tms/1.0.0', timeout=120)
    >>> service.identification.title
    'Tile Map Service'
    >>> service.identification.abstract
    'A Tile Map Service served by GeoWebCache'
    >>> service.identification.keywords
    []
    >>> service.identification.version
    '1.0.0'
    >>> service.identification.url
    'http://maps.opengeo.org/geowebcache'
    >>> len(service.contents) > 0
    True
    >>> tm = service.contents['http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A4326@png']
    >>> tm.title
    'bluemarble'

you can filter the contents by profile and srs:
    >>> len(service.items())
    14
    >>> len(service.items('EPSG:900913'))
    7
    >>> len(service.items(profile='global-mercator'))
    7
    >>> len(service.items('EPSG:900913', profile='global-mercator'))
    7
    >>> len(service.items('EPSG:4326', profile='global-mercator'))
    0
    >>> sorted(service.items('EPSG:4326'))[0]  # doctest: +ELLIPSIS
    ('http://maps.opengeo.org/geowebcache/service/tms/1.0.0/blue@EPSG%3A4326@png', <owslib.tms.ContentMetadata object at ...>)

The details of the TileMap are fetched on demand
    >>> tm._tile_map == None
    True
    >>> tm.title
    'bluemarble'
    >>> tm.abstract
    >>> tm._tile_map == None
    False
    >>> tm.srs
    'EPSG:4326'
    >>> tm.extension
    'png'
    >>> tm.height
    256
    >>> tm.width
    256
    >>> tm.mimetype
    'image/png'
    >>> tm.boundingBox
    (-180.0, -90.0, 180.0, 90.0)
    >>> tm.origin
    (-180.0, -90.0)




You can get tiles by their x,y,z indices, the title of the tilemap, projection and mime-type
    >>> service.gettile(10,10,0, title='bluemarble', srs='EPSG:4326', mimetype='image/png').geturl()    #doctest: +SKIP
    'http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A4326@png/0/10/10.png'
    >>> service.gettile(10,10,1, title='bluemarble', srs='EPSG:4326', mimetype='image/jpeg').geturl()   #doctest: +SKIP
    'http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A4326@jpeg/1/10/10.jpeg'

if mimetype is ommited the tile is fetched from the first TileMap found:
    >>> service.gettile(10,10,1, title='bluemarble', srs='EPSG:900913').geturl()    #doctest: +SKIP
    'http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A900913@jpeg/1/10/10.jpeg'

You can also specify the Tilemap by id:
    >>> service.gettile(10,10,0, 'http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A900913@jpeg').geturl()    #doctest: +SKIP
    'http://maps.opengeo.org/geowebcache/service/tms/1.0.0/bluemarble@EPSG%3A900913@jpeg/0/10/10.jpeg'
