well the value of obscuring your OS type is debatable, but the way to do this 
is with the right firewall ruleset.  This is debated over and over on the 
[EMAIL PROTECTED] mailing lists.  Search their archive for more information on how 
to do it.

SOP in this list is to put questions on different topics in separate emails.  
puttng proper subjects for each question helps the archives be more useful.

if you want to contribute other than translation, the besst way to fnd 
something you can contribute to is to spend some time on questions, and a few 
of the other mailing lists, until something comes up that you would like to 
do.  Of course read the handbook and spend some time looking through the 
website.  If you do you'll find the projects webpage that probably has 
something you can contribute too.

Send an email offering help at [EMAIL PROTECTED] and read the documentation 
project pages.  They are accessible off the FreeBSD.org main webpage.  They 
would love to have your help, and can direct you to where translation help is 
needed most.  Actually if you just read enough of the handbook and the 
Russian version, you would see many things that haven't been translated yet.
We'd all be glad to have your help actually, so have fun.

Nobody is going to be able to read kern.ostype from your system unless
they have already rooted you.
