Subject Re: [PROPOSAL] Apache OpenMeetings incubator for Web Conferencing
Date Thu, 29 Oct 2009 13:18:00 GMT
Hello Martin,
I may fail to understand Paul's question, indeed. Let me give my best
try to answer to your questions.

> Is it not true that OpenMeetings requires Red5 in order to function
properly?
True.
The Openmeetings requires Red5 to function properly.

> So that, if we cannot distribute Red5 as part of an ASF distro, because of the license,
we also cannot distribute a functional
OpenMeetings product?
Not true.
Openmeetings can be distributed without Red5.

>  Or is there some alternative to Red5 that could be distributed instead?
I believe it is possible to use Adobe Flash Media Server as a
substitution for Red5, but we cannot distribute Adobe FMS that for
sure.

In your last question you assume that we cannot distribute Red5. I
don't think this is a valid problem.

1. Anyone can distribute GPL-licensed binary, or LGPL-licensed
library. The virus problems begin when you try to modify the source of
the product. This always requires proper attributions in COPYRIGHT
file, but anyway.

2. Apache may have more strict guidelines on distributions. Nothing
prevents us to write a small Apache-licensed Red5 installer and
distribute it instead.

3. The truth is that currently Openmeetings is not built on pure
Apache stack. I cannot see a problem here. Most Apache products used
Sun's java when there was no Harmony, and Sun's vm was not even FOSS.

Since I'm not a layer, I can be mistaken here. Martin, please, let me
know, if you find error in my conclusions.
