Hi!  Team yaSSL has been considering the addition of the GOST block cipher to our wolfSSL embedded SSL library.  If you are unfamiliar with GOST, there is a great wikipedia article here:  http://en.wikipedia.org/wiki/GOST_(block_cipher).  If you think wolfSSL should include GOST, then let us know.  We appreciate your feedback.  Just contact us at info@yassl.com.
