[Bf-python] Embedding Blender - XEmbed protocol

[Stuart Axon]

This looks pretty cool.   I've been thinking a bit about a remote graphics 
library that could work with Blender or maybe other things, like remote gimp 
invocations.

Unfortunately I don't have time to write it (and won't for quite a while).


It looks like you could have celery running on both ends and have it handle 
passing the data around, that should sort out some of the limitations.
If you can get dir() and help() working from the remote python, that would be 
really nice for development.

If other types of data can be sent then it opens up some very interesting 
possibilities for integration (using blender as a library from outside apps, and 
possibly integration with other graphics libraries).

Using the Save Runtime functionality could be quite interesting, if that 
contained a script that waited for a connection.


I'd imagine the bpy api letting you either automatically start a blender 
instance, or specify an address and port to connect to one on.
