When we started to develop our application (aka PyMAD), we had in mind to
push the instrument responsible to dig into python, and offer him
something closer to a framework, rather than a end-user application.
This, because this guy is someone with 1000 ideas per hour, and often asks
for new stuffs. So, giving to him such (very) high level tools to control
his instrument could have been nice.
But He never dig enough into python to be able to do so. I don't blame him
at all, as it is not easy to change habits. Python was new to him...
But he is about to retire, at the end of this year, and the new
responsible is younger, and uses python to treat his scientific datas. So,
I think it could be nice, this time, to implement what we always wanted to
Saying this, it appears to me that we don't really need a RPC-like
framework, and exposing all the internals of the application could be
great. We will have to find a mecanism to hide some parts for simple users
using the instrument, to avoid them to brake things during their
experiment (:o/), but I think it can be done without too much work.
On the other hand, having the jupyter mecanism, and being able to start a
session from one place, in a pure console, or in a qtconsole, them
go back home and switch to a web-based console to continue to work from
the same point is really great.
Last, it appears that Pyro4 dropped some features mandatory for our
application, like the event service! So, we are stuck to the 3.x version...
That's why I want to explore this idea.
