A new SslStream class will be available in Fx 2.0.

It depends on your imagination, e.g. it never made me any coffee ;-)
But it can be used as for client and server side SSL3/TLS1 sessions,
including support for client certificates.

No, it's available under MIT X.11 license (like most of Mono's class

MIT X.11 has very few restrictions - but I do recommend anyone to read
any license before using binary/source code.

No, it will work with both Mono and MS runtimes/class libraries.

Mono doesn't ship with any trusted root certificates (in parts because
of license restrictions). You'll need to provide them directly (e.g.
source, install...) or indirectly (instructions) with your application.

See previous comment about "technical issues".

There are several closed source libraries that offer SSL/TLS. Mentalis
also has a open source SSL implementation for .NET.
