What are your technical challenges?
 

So what are the difficult technical challenges you're facing? Features you'd love to give your customers but that are difficult to implement? Manual repetitive work you'd love to have automated?

Video protection is probably the biggest one for me but it's not something that bothers me much.

I think the biggest challenge overall is not a technical matter but a matter of time. There are so many things that require optimizing but it takes so much time to see the results.

Interesting! What part of video protection are you looking for? Are you a content producer, free site, paid site, ...? Are you looking for solutions like watermarking and automatically filing DMCA's? Or are you looking to thwart deep linking? Or blocking downloads? Manual downloads or automated scraping?

automated scraping. KVS has nice protection but I just don't know how to reimplement that on WPS. But again, its not a big deal and not worth the time to figure out.

Time is the only real constraint.
