There is no reason this can't be done on Limewire. It is nothing to do with Shareaza or Limewire in fact. People can share what they like on either.
HOWEVER There are a lot of zip files and application files out there containing viruses and a lot users do not seem keen on touching them for that reason. Album wrap or ALBW is the way most people share albums as far as I can see.
If you're interested this thread tells you more.
