wow thats cool... and fortunately for you the application to send to is nokia/hildon app wonder why they didnt wire that up before

Thanks for insight to the Action Handler / uri-actions-default linkage that might be good way to expand dbus-switchboard for non-hildon apps.

I have built a new version with modified dbus-switchboard.desktop and added some entries to apps and xref files. Installer will overwrite apps and xref files so backup if you need to.

Download v1.1.1 here :
http://wardenclyffetower.com/MaemoFi...-1.1.3.all.deb

Then for YoDude, you should be able to just edit (as root) the /usr/share/applications/uri-action-defaults.list file and set the mms line at top to :
mms=hildon-dbus-switchboard.desktop

Then reboot and it should work.

As a side note : comix/cbr files (which does have a real mime type just no previous handlers) will work right away from file manager if you open/with and choose dbus-switchboard (because its in the apps and xref files). For automatic selection edit /usr/share/applications/defaults.list adding mime type application/x-cbr=hildon-dbus-switchboard.desktop and reboot

And files with unknown mime types (tap and hold menu/details) application/octet-stream can be universally associated to dbus-switchboard in defaults.list

So to send to non hildon apps :
Web Protocol/URI Handlers : edit uri-actions-default.list
Web MimeTypes : edit defaults.list
FileManager : open/with and pick dbus-switchboard everythime or permanently edit defaults.list
