I can't offer anything more official than my 2 cents...
The clients that are distributed are only useful for attempting to 
decrypt one specific message.  They are useless for secure 
communications since there is no 'encryption' routine.  The 
decryption code is virtually identical to that distributed on the RSA 
ftp site as an appendix to the Rivest paper (which does include 
encryption code).  I doubt it would be there if it wasn't permitted.
