I tried emailing that address and didn't get a reply.
But I think that could be a rather cool idea - something like REST over SMTP? Know a single email address, send it a blank email get back and kick off the whole HATEOS process - which actually might more sense for something like this rather than over HTTP.
Ah yes - I was being a bit thick and I hadn't read your blog post at that point.
NB I left a comment there but it didn't format correctly. What I suggested was having the subject line be similar to the first line of an HTTP request i.e. <verb> <path>
