As said, I think a gateway in http://Cspace.in is not necessary, as we mix up secure and insecure chats and Cspace needs other development than multiprotocol, though, other jabber clients should integrate Cspace, either as a code to get a multiclient or with a transport. The suggestions are quite fitting, but I think you did not get th earchitecture of CSpace, so test around please.

You do not seem to understand purpose of jabber. Why is cspace something
so special we should care more than with other IM networks?

Between, try meet someone ask him to dictate you his public key ;-). I
remember my JID.

This would mix up the system, so only the client can integrate CSpace as a hybrid version.

Well, is it possible to run more your clients on a same computer with
separate keys? Like on a unix system, two logged-in people, having each
his own? If no, then I think your system is broken.

If yes, why could not the transport have all the private keys of the
users (OK, it is not too much secure, I know, but no transport is, you
have to give it at last password or so..) and act as many clients on the
same machine?
> This is requested and recommended, and if two users could switch to cspace in Jabber to jabber client, than they should leave jabber for secure Cspace protocol... of course this is very acid to jabber as here a leave of the jabber identity is necessary...  But otherwise I see ne technical solution, if you have no idea to this problem.

I want to see all these jabber-only clients do that :D. That just makes
no sense. Being you, I would ask the multiprotocol ones.

IMHO they can not get hybrid. Implementation and religious reasons.
> There was a long time ago the question for encrypted jabber, why we need servers, if they route white node traffic, they cannot read. So a server architecture of encrypted messages is nonsense and they could to it IP to IP. They only need a lookup service to get the IP adress or RSA-key of the client.

Um, and where would all the transports, all the services, dictionaries,
offline storages go? No, you made entirely _new_ protocol, that does not
have much to do with jabber. Jabber is server-oriented. You can hardly
turn it inside out. You can get inspired and define a new protocol.

Between, speaking about redefining protocols, you should go to JIG, not
JDev.

If you asked me, this will not fly. You need to persuade all jabber-only
clients to include cspace. They will say "Um, why? Another foreign
network, we do not care." And you need to define some binding between
jabber and cspace. 

Between, even this approach has some disadvantages by itself. You can
not just go to friends computer and log on by name and password you 
remember. Do you have contactlist that you would download each time you
log in? Do you support offline messages? Normal users just do not care
about security. That is why they still use networks like MSN or ICQ,
they are totally unencrypted.

This is a terroristic email. It will explode in 10 minutes,
