Is the SILC protocol still used? I'm looking into implementing a private SILC server for friends (and possibly their friends).

And after visiting the Wikipedia entry for SILC protocol, it seems all the official pages linked at the bottom are dead with only a few anon servers here and there.

Is it still being used nowadays?
And if it is ... where(online) are more resources (howto's and/or daemon software)?

And if it isn't used anymore... are there any security reasons involved?

Is the security model or the used cryptographic protocols and algorithms flawed thanks to exploit XYZ?

A complementary question would be: are there any more current alternatives available now?

another complimentary question would be:are there any public and/or anon servers still online ?

and ..does it use much system ressources on a server let's say for 50 concurrent users ?
(this is just a complimentary question if you feel you can answer :)
Yes, SILC is still used daily by a few of us die hards. :-)

I, too, noticed the other day that the official source repos are dead. Perhaps we can get them up on Github or other hosting site.

I haven't heard of any flaws discovered in the protocol itself, but I haven't heard of anyone reviewing it lately either.
