Nokia's MWS was a mobile web server and Python-driven CMS, pushed thru a Nokia-maintained gateway. The latter being because per their relationships with carriers, the use of a DNS gateway on one's mobile device meant that a user could literally skip the carrier they were on and do other things. Nokia played fair there, but nothing else was on their server. Samsung took everything except the server/gateway side of that tech and made Kies Air - a slightly detuned but smoother CMS over WLAN hosted from your mobile that allows for the management of various aspects of your mobile w/o pulling it from your pocket.

The point of a sever and CMS on your own mobile device - both which were built with open framework, open licences, and open source technologies and behaviors - is that you can manage all of this yourself, without exposing yourself to others.

If people could make it themselves always, then we'd not be having this discussion, because Maemo and the N810 would have been enough. Per the warts of the DIY community, not everyone can - but those who can rarely make it accessible enough that even those w/o their bent can do it. That's the entry point the MWS proposed. It was missed here and especially at Nokia (ask the Jolla board member who was one of the 4 people who created it).

Having a server and CMS on your mobile device means that you can create and maintain connections yourself. Every mobile is capable of it, every carrier restricts some important point of it in their terms of use. If people were responsible for this aspect of connectivity and mobility, there'd be a lot less of that central control.
