few minor improvements:
- Add trailing slash in the URL of osmarender tiles
   <tag k="tiles" v="http://tah.openstreetmap.org/Tiles/tile"/>
   to have it written uniformly
- minZoom (defaulting 1) & maxZoom levels (mapnik vs. osmarender tiles)
- bbox (if limited to not cover whole world, such as slovakia)
- slippy URLs could include layers parameter to go directly to that 
layer in browser

Maybe adding lat, lon & zoom parameters would also go to specific 
location...khm, but parameter namse can differ over sites, so it would 
have to be sth like

http://www.openstreetmap.org/?lat={lat}&lon={lon}&zoom={zoom}&layers=0BFT
but that won't work if parameters are not known (url 
http://www.openstreetmap.org/?lat=&lon=&zoom=&layers=0BFT shows nothing)
, so they'd need to be taken out or have all that info in an additional 
parameter named slippyPermalink or so.
(eg i want my phone to send permalinks, not just coordinates, so that 
recipient can go directly to my cycling/skiing/road map and see my 
whereabouts).

Permalink URLs accepting degrees or some arbitrary openlayers units as 
parameters is another issue, out of the scope here.

Is that stored in some db? It could be put in main db as nodes tagged 
with config=slippy_map_layer and all other keys? Clients could then 
fetch it from osmxapi ... that would be convinient, but abusing the main 
DB and opening clients to abuse by editors :)
Probably having it in SVN is better than abusing the DB.
