Why not Openlayers ?
Despite the look of Ka-maps, there is the problem of Ka-maps not having an API and at first the code looked a bit confusing.
So I have a look at Openlayers, they seem to be more organized than Ka-maps but I didnt liked that the server requests are based on WxS and there is no PHP as "back-office", never the less the options given like the connection to google and virtual earth extremely interresting.
So in the end I started to work with Ka-maps
