Yea, my company paid for my trip, hotel, and conference fees.
Pycon, through the support of all the sponsors, is actually fairly cheap. Only $300 to attend, and they did an amazing job organizing it. Lunches and breakfast included. I know of other tech conferences that are much more expensive.
I think it could be easily argued that sending employees to things like Pycon directly benefit your company. We work in a really fast moving industry so it's a necessity to keep employees on the ball. Going this year I learned a ton of new things about Python that made me more productive.
I was a tutorial presenter — I have a startup and a tiny tiny salary, so my company was not able to subsidize the trip. I did however get a big financial aid grant from the conference/PyLadies.
