I am giving up any thoughts on trying to get the existing microb modules (maps, ssoautologin) working on newer Gecko (even with wrapper libs). Too much has changed (e.g. removal of nsIProxyObjectManager to name one thing I have seen) and possibly also even the basic ABI of XPCOM has changed.

So basically the way forward for adobe-flashplayer, tablet-browser-default-plugin and tablet-browser-mediaplayer-plugin is to restore the NPAPI function linked to previously somehow. For libssoautologin, we need to figure out what it does and if we need it, clone it (its probably possible to clone it), And for maps, we need to A.Clone it completly, B.Clone it partially (i.e. clone it but pull the old stock lib file in as a shared library to grab code we cant clone), C.Find a way to keep old Gecko (or a rebuilt/modified version of old Gecko) around just for maps or D.Forget Nokia Maps and replace it.

In terms of a replacement what I want from a maps client is offline map downloading (not just caching but proper "download everything for this area over this high-speed DSL link and only download new stuff if its changed" ala Nokia Maps) without needing to manually input specific coordinates/sizes for the map (I want it to know what "Australia" or "Brisbane" is and download it for me, just like Nokia Maps does). Google Transit GTFS data set support would be awesome (i.e. being able to display bus stops etc on the map and see all the services going from those stops and when) as would a nice sane address/location/poi search. Don't need turn-by-turn or voice navigation since I dont drive a car

If such a maping program exists (or can be made), it would mean I could get rid of Nokia Maps for good.
