Hello!
thanks for this code, i'm currently using in on my app. i've just found a problem, when building the app with "Ad hoc" certificate or distribution, the app crashes, due to a erron on socket.io class.
i've found this error on similar code ( nowelium/socket.io-titanium#10 ) and this is also present on your code,

i've just modified line 1311
from: +new Date
to: new Date().getTime()

this solve the problem, at least my app don crashes now
