[SCIM] Issues of multi user server

Hi,

> 1) A totally library based input method may get very large memory 
Japanese have same problem too. However, could you use mmap'ed file to
share data between processes? For example, my conversion system Anthy
3.5MB dictionary file, it allocates 200KB for index data and 200KB per
a context when you activate it.
Anyway, I can agree to per user server. But I want input method system
to allow purely library based implementation which do not incur communication
overhead.

How about using X's session management protocols? More simple way is to
connect X server at login and run until the connection goes invalid.

Thanks, I am happy to hear your opinion.
