I hope Twilio decides to support inbound/outbound faxes. I only need to send and receive faxes a couple times a year, and I would love a pay per use fax service. Every inbound fax-to-email service I've seen uses a subscription model and wants to charge me $10 a month plus setup fees. The only suitable option I've seen so far was faxaway.com, but I can't tell if they're still in operation. I tried signing up online and was hit with the weirdest catch-22 I've ever seen: they wanted me to print out the application and fax it in.
