I've done this for clients as part of projects (automated firmware flasher sort of stuff) but never thought of offering it as a service. People definitely do do this (I know people have done for HTPC stuff, and as VPN boxes, and for adblocking) but I haven't seen it at scale. If you're interested, email me and we can look into making it a product.
