I think it is stated cleanly in the Open Software License (v2.1):
5) External Deployment. The term "External Deployment" means the use
or distribution of the Original Work or Derivative Works in any way
such that the Original Work or Derivative Works may be used by anyone
other than You, whether the Original Work or Derivative Works are
distributed to those persons or made available as an application
intended for use over a computer network. As an express condition for
the grants of license hereunder, You agree that any External
Deployment by You of a Derivative Work shall be deemed a distribution
and shall be licensed to all under the terms of this License, as
prescribed in section 1(c) herein.
The provision comes from a similar one in the Real Networks Public
Source License (p.195 of Larry Rosen's _Open Source Licensing_).
