I do support an encryption feature for MP!L too.
Privacy through encryption is and will be in future a big topic. To say "I don't care if others can read my conversations" is very careless in my opinion.
I think an encryption functionality inside of WLM will make it even more attractive and actually in my opinion encryption features should be a very basic of every new IM. Pidgin, Kopete, Miranda, Adium, etc. are using message encryption (in this case OTR Messaging) why not MP!L?
I took a look on SimpLite-MSN but in my opinion this is not a good solution.
I would like to suggest OTR (Off-the-Record Messaging)
http://www.cypherpunks.ca/otr/ as a possible candidate for encryption. It has the advantage towards PGP that is supports PFS (perfect forward secrecy) and "deniable authentication" and it stands under the LGPL, so it's free the use.

This is not correct. Like OTR everybody can look how the encryption is working but as long they don't have your privacy key they can't decrypt your message (well they can but I think they won't life long enough to see the result as it might take.. "a few years" ... ) And as OTR is using only temporary keys nobody will be able to decrypt closed conversations (PFS).
I can only beg the MP!L team to think about an implementation of message decryption because it is definitely a serious topic, for now and in the future.
A worried user.
