I've updated the specification in the cvs repository.

Crossed out text = my suggestions for removal.
Underlined Blue text = my suggestions for addition/change

At this point most of the suggestions are directed at cleaning it up and
having it reflect more of a technical readability. Also, rather than
using rtf (if you have msword) can you convert the document to msword
2000 format? This way we can take advantage of change tracking. Then you
can approve or disprove changes more easily as well.

Comments on some of the suggestions:

	Rather than ending requests with \r\n I suggest using only a ;
	In addition rather than using full length words for requests (control
commands)
	I suggest using bit flags. This will be a significant improvement (on
the server side mostly ) in the consumption of bandwidth and cpu
processing. I?m thinking 500 users connected sending requests
simultaneously. This is not to say scrap the terminology (I think they
are perfect ways to name the functions we call to perform these tasks
within the client and server). Rather than the request looking like this:

	REQUEST VWPCORE: Such <in, such, action>\r\n

	it would amount to this:

	// our bit

	 _ 7 _ 6 _ 5 _ 4 _ 3 _ 2 _ 1 _ 0 _
	bit 0 flagged means REQUEST
	bit 1 flagged means VWPCORE
	bit 2 flagged means VWPTERRAIN (and so on)
	bit 4 flagged means GET

and the final request is:

	0x013 <args, right, here>;

Let me know if you think I'm going overboard in worrying about the
impact of this on bandwidth or cpu. My view is that we are not working
on an http server, or even a mail server that performs a quick service
then closes the connection, these connections will be constant with data
and actions continuously being sent back and forth. It's my view that we
should streamline as much as possible (at least where the server is
concerned).

Talk to you later.

Hi!

I think we should implement the vwp_protocol as
plugins that way we could be able to share some code
between the vwp_server and client. And it will allow
for easy upgrades. Also,we will not have to release a
new client/server for every protocol update.

Because I want everyone to be able to use vwp, I have
been trying to implement wxLocale to provide
internationalization to the VWP Client. However, for
some reason, when I load a catalog the call to
osgDB::readNodeFile doesn't work. If you can get it
working or can spot some obvious bug please fix it.
The new source code is at
http://vwp.sourceforge.net/vwp.tar.gz . I have
included a windows makefile and a catalog with french
translations that I got from BabelFish. 

Thanks!

PS: does OpenSceneGraph use gnu gettext?

Hi!

If you read the VWP Specification, then you would no
what a request set is. I was thinking to put the
request set implementations inside window's dlls and
Linux shared objects. I am not too familiar with
linux-dev(I have only used linux for about 4 months).
I am especially unfamiliar with how Linux uses shared
objects files(the realname, the soname, the linker
name , and ldconfig). So could any of you explain them
to me? Do I write the Linux so file sources in the
same way I write them on Windows?

Thanks for all your help!

Okay, this is the promised email.

All that I have done so far with the vwp client is
getting osg to display stuff on wxGlCanvas's. Now that
that works, I think the next goal should be to design
the protocol, which I am currently doing right now.

Once the protocol version 0.1 has been completed, you
may start work on the server or you can help with the
client. If you wish to start the server then I must
ask that you use the wxWidgets toolkit so as to
mantain cross-platform support. If you do not have
experience with the wxWidgets toolkit then go to
http://wxwidgets.org and there are also some
interpreted language bindings that will help you learn
the wxwidgets classes. One of these is
http://wxbasic.sourceforge.net

Attached you will find the introduction to the
VWP(Virtual World Project) Protocol Specification in
Adobe PDF form. If you want it in text form I can
convert it for you. But I think there are Adobe PDF
readers for almost every platform.

Email back if you have any questions!

Travis Athougies.
