From version 518, MAPC2MAPC will access some Web Map Servers (WMS). There is a description of WMS at  http://maps.peterrobins.co.uk/wmshowto.html (although not all of the links still work).

MAPC2MAPC can use WMS as a map source (File>Build map from map source) provided that the server supports Web Mercator (EPSG:4326) - most do.

Having found the URL to retrieve a tile, configure this as a map source :
  Replace the EPSG code by 4236
  Make sure WIDTH and HEIGHT are both 256
  Replace the bounding box (BBOX) parameters with {b}  (eg ....&BBOX={b}&WIDTH=256....)

As an example, here is the code for IDEE Spain :

http://www.idee.es/wms/MTN-Raster/MTN-Raster?LAYERS=mtn_rasterizado
&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application/vnd.ogc.se_inimage
&FORMAT=image/jpeg&SRS=EPSG:4326&BBOX={b}&WIDTH=256&HEIGHT=256
