It seems to a good way. I had been thinking about same scheme
after I post (so I note "waiting for YamaKen" in follwing TODO
item).

- we want something to know available input method names
  (waiting for Kazuki, YamaKen)

Did you say about not caching something in the memory but
avoiding unnecessary list generation? If so, it's a good idea.

Comparing mtime of plugins/input/ and qt.immodules file is a
efficient way. We can automatically kick qt-query-immodules or
the equivalent code in the Qt application process based on the
result.

My annoyence about the list generation is resolved as
following. Takumi, how do you think about it?

- who should generate the list?
  -> qt-query-immodules or the equivalent in Qt application
     process

- when should generate the list?
  -> when any Qt application starts (regenerated when actually needed)
  -> when new plugin installed/uninstalled (optional)

- users are required to find existence of qt-query-immodules
  -> not required because any Qt application kicks it automatically

- input method plugin developers and packagers must kick
  qt-query-immodules properly on installing/uninstalling
  -> not required because any Qt application kicks it automatically
