It is possible, but not with one and the same application. Currently the
setting for remote-capi is done per-user. Of course, this can be changed. 
But if you want to merge local and remote CAPI, then it is not possible at 
the moment. This would need enhancements.

I have tried it, but I didn't really test it with Asterisk yet.
I use it, but with other applications like a standalone voicemailbox
and capifax.

The connection is TCP, so no problem with reliability with that. But
the perfomance depends on the IP connection.

I didn't test this yet. But I assume the client libcapi will signal
error codes when the connection is lost.

I'm sure, if someone really wants to use this, some enhancements 
must be done for the faulty cases. But it should be easy.
