Junk, junk, junk!
We bought a very expensive license for this and what a huge mistake. Browser plugin in version 7.2 is still 32 bit only, so we need to tell out clients to run in 32 bit - how unprofessional.
UDP is not a default option, you'll need to pay more for that.
Error messages are cryptic and unhelpful.
Pre sales support is great, after sales sucks.

We tried to do it cheap with Mass Transit as Aspera is more expensive. We burned our money. Aspera is going to replace our Mass Transit server after all.
