Re: Programmatic and security models for IoT

Someone pretty please summarize: If I want to write (a) secure as
possible today (b) yet still interop with the libraries I will want
[yes, that will probably insert security holes, I know] all (c) in
javascript and (d) won't dry up over night leaving me stranded with an
unsupported compiler...

...then what do I download & install? Caja? SE5? SES? Waterken?
Something else? :-) As a Joe Programmer In The Street, what is the
simplest way to get started?

thank you!
