XEmbed ipc semantics

[Andreas Aardal Hanssen]

It would be very useful for XEmbed to support simple ipc messages to be
sent between client and embedder.

- A line edit may want to send a line of text. 
- A button may want to emit a signal / trigger an action in the embedder.
- An application may want an embedded browser to fetch a URL.

Has there been any research or work done in this field, and if so, can 
anyone point me in the right direction?

Andreas
