I've pushed Twisted on a 100M US company about 7 years ago and it has continued to work for us big time. The code - tens of thousands of lines in 20+ servers - survived Twisted upgrades for all these years without any changes (OK, there was one related to import, had to add PYTHONPATH=. to env). Kudos to Twisted team!
