IPython has a great concept of comm objects, which are basically pairs of objects - one on Python side and the other in JavaScript - which pass messages between them allowing for underlying widget objects to be transformed in unison on the server and client sides.
I'm planning to reuse the same concept in an application I'm writing, so I'm considering simply reusing the actual implementation from IPython rather than writing one of my own. Does anyone have any experience that, and could provide me with some suggestions and caveats?

If we talk about resources, memory, legibility what would be better between:
Create all the instances at the beginning of a method? (left side of the screenshot)
Create the instances as we need to use them? (right side of the screenshot)
Do you have any documentation that says which is better? I searched in the Python documentation but found nothing.
Well in python creating instances is creating instances, regardless of where you do such, the same amount of instances will be created taking the same amount of storage space.
If you're looking into memory conservation I'd recommend using the del operator when instances are no longer needed.
Other than that this is totally just up to personal preference, and how you'd like to format your code.

I would like to use Python for my project but I need to distribute the computation on a set of resources.
You can try with pyCOMPSs, which is the python version of COMP superscalar.
More info here
With this programming model you define which methods are candidate to be executed remotely defining the direction of the method parameters (IN OUT or INOUT). Then the main code is programmed in a sequential fashion and the runtime analyses dependencies between these methods detecting which can be executed in parallel. The runtime also spawn the exectution transparently to the remote hosts and do all data transfers.

Is there any known way to do realtime collaboration stuff (like Google Docs) in Python (not thru the browser)? I'm working on a program, and would like to add said feature to it.
Thanks
You can try Dweet, which is a service that stores JSON data in key values pairs. You can use one of the client libraries listed on their website or you could simply make a request like so:
urllib.urlopen('https://dweet.io/dweet/for/my-thing-name?dweet=awesome')

I was wondering if there is a proper way to periodically check an api for updated data. I'm looking for a more efficient solution than a while loop with a delay timer.
Are there any standard headers that can be checked to see if content was updated (in order to skip comparing previous results to the new ones?)
Additional notes
I using python at the moment but this is a broad question regarding all programming languages.
You probably want to look at the Conditional Requests spec and the Caching spec.

I'm trying to write my own protocol so that multiple servers can pass data and connect with each other, kind of like mongo://. I have been looking at TCP & I understand ports, but how do I write something so that people can just do something like connect("proto://example.com:6767/") ?
Also, I'm writing in python.
Thanks!
I believe you need to look into urllib2 and writing a subclass of BaseHandler, specifically the functions protocol_request and protocol_response.
Whether the way urllib2 handles request/response cycles suits your application is up to you to decide -- it may or may not be exactly what you want.
