May be, I even will agree when something will be at least planned ;-)

This is answer I got :-) May be there were more messages after that, I 
didn't read them , sorry.

Right.

Anyway, are there any plans to implement i-frame switching? :-)

We did tests with jitsi, just because it is mentioned as tested in
asterisk wiki.
( https://wiki.asterisk.org/wiki/display/AST/ConfBridge+10 )
I don't know does it support rfc5168 :-(

But is this planned?

You just wrote that asterisk doesn't support this feature, so why use 
wireshark?
Sorry, I'm not programmer, I'm just system administrator, I can do some 
tests or small patches, but implemeting feature- sorry, I can't for 
obvious reason- I have no enough skills.

According to wiki and our tests Ekiga doesn't work with confbridge video 
at all, don't know about other clients.
