Hi there,

Diffs and other improvements that affect bandwidth requirements should be complete in the next two months, before we announce pricing. Our agent requires standard web ports, so a firewall that allows web browsing should allow a device to connect. We are funded by a well-known Silicon Valley VC, this will be announced in a few weeks.

Pricing isn't finalised yet (will be announced in 2 months) but drop me an email at alexandros@resin.io and I'd love to let you know our current thinking.
