Hi,

Thanks a lot, you make me more clear about the framework.

Does this mean that we could use only one plugin for onscreen or hardware, and if we implement a plugin like the VKB, and then we should set it in the gconf to make it used. So the original VKB plugin will be replaced and we should reimplement a VKB.

It seems that make a similar plugin and make it be used by the VKB is a better way, do you plan to use this way to support the CJK input?
And how could make this plugin be used by the VKB plugin?     The plugin for input method is different from the VKB plugin and where it be put? also /usr/lib/meego-im-plugins or any others?   
I am puzzled about the relationship between this kind of plugin and the VKB plugin.
