[Telepathy] Pictogram support (Montreal Summit)

[Cesar Mauri]

Hi all,

Recently I suggested to Meg Ford, who was attending the Montreal Summit,
to ask Telepathy developers whether it would be possible to add support
for pictogram based communication.

Here is my suggestion:

And here Meg's answer:

Regarding the feasibility of implementing such a library on top of the 
supported protocols, Meg also told me:

And so here I am. My questions is:

- Do (most commonly used) supported protocols allow for sending 
arbitrary images along with text? Otherwise it would be pointless to try 
to write a library for this.



Thanks.
