Hi Marcin,
I tried to respond to this email, but in all honesty, I can't follow
your line of argumentation. Maybe you can list your main points as a
list (sorry, I'm a bit simple)...

>From what I got, I agree that WARP is over reaching: It does not
address the requirements it lists from the Widgets 1.0: Requirements
document. Otherwise, I'll just leave it to Robin to respond.

I've made some notes on the proposed changes.

What you did in 192 characters, the access element does in 52.

That is the point of the access element: to make these kind of
annoying declarations easy to write.

I.e. assuming that the network access is conditional, what are the implications for the widget's code and author in case the network access is not present or its presence is dynamic? (e.g. provide a definition of the event mechanism).

Other schemes, like sms, tel, mms (there is no RFC for some) have their own specificities, e.g. country calling/dialing codes, shortcodes.
