My question revolves around using XML and binaries (i.e., pictures, sound files and avis). I realize the preferred solution is provide a link and let them download the linked file. However, should that not be possible and it is necessary to transmit the actual binary, how would I do this? Do you recommend conversion to Base64 encryption, serialization or another method?

It depends on how you're transferring the message from the server to client (or vice versa). If you're using Web services, you should definitely read Matt Powell's article at MSDN as it explains all the issues related to that. If you just have to put the binary elements into a regular XML, then Base64 is your only choice. Beware that Base64 is NOT encryption -- it's just encoding. You will have quite a bit of size increases using it, but it's the most compatible. If you couple it with compression (i.e., using the #ziplib, you will be OK.
