You didn't post your full resume, but as a hiring manager I can tell you that the telecommuting preference and the previous listed experience as CTO might have disqualified you from a number of companies, even if they are presumably open to distributed development and multiple levels of talent.
On the other hand, the fact you didn't receive a response at all from so many (we typically send a note to every applicant who makes the effort to contact us) is surprising. Many companies use a tracking system of some sort to classify and manage recruiting workflow - most of these are utter tripe.
in my experience, they don't bother to send a reply. The way I see it, if you apply for a job that was advertised it's good manners to reply. If you send in your CV unsolicited then it's fair enough not to hear back.
