* An interface representing a channel which will have to execute some sort of

* program provided via its URI to compute the data it should return.

*
|
|
* If a channel implements this interface, the execution of the program in
|
|
* question will be restricted in the following ways:
|
|
*
|
|
* - If the channel does not have an owner principal, the program will not be
|
|
* executed at all, no matter what. This is necessary because in this
|
|
* circumstance we have no way to tell whether script execution is allowed at
|
|
* all for the originating security context of this channel.
|
|
* - If the channel has an owner principal, how it is executed is controlled by
|
|
* this interface. However if the owner principal does not subsume the
|
|
* principal of the environment in which the program is to be executed the
|
|
* execution will be forced to happen in a sandbox.
