why go ?
go is easy to deploy. single binary file (but they are large, i guess that will be somewhat fixed in 1.3v).
i feel more safe in go than python. error handling in go is better compare to other languages.
speed & concurrency.


why not go ?
require more developer time.
JSON decoding/encoding in golang pain. you need to map json data with a struct.
lack of library

chose python if
you care about development time.

chose go if
you care about performance, safe code and development time.

> Send these info to a server using HTTP, as XML & JSON, when it changes.
> Periodically Connect Server using HTTP and Get data as XML/JSON

golang HTTP library is nice. where on other hand in python you have to use requests.


> Have a long lived connection which listens to the server, using TCP.
> Run a service (daemon) at the background the whole time.

this is where golang shines

this seems like a small project i guess golang will work fine.
